海外TECH	DEV Community	Sequential GUIDs in Entity Framework Core Might Not Be Sequential	https://dev.to/connerphillis/sequential-guids-in-entity-framework-core-might-not-be-sequential-3408	Sequential GUIDs in Entity Framework Core Might Not Be Sequential The BackgroundOur customers more often than not chose to host our application on their own machines so we frequently get asked what the minimum hardware requirements are We based the estimates we provide on the requirements of similar applications With our latest release we decided we d get a conclusive answer for ourselves so we put some resources into running benchmarks We settled on a simple setup Write a simple script that would simulate a series of requests that would run through hot paths and see how many operations we could complete in a fixed time frame The script would run X number of concurrent requests for N minutes log the statistics to a CSV file and export our results to a CSV file for analysis We architected our test server to simulate an organization stressed for resources On a single virtual machine we installed SQL Server IIS and our application For the hardware behind the virtual machine we used an Azure Fs v vCPU GB For our warm up we ran the script with concurrent tasks for minutes the results that we got total requests completed form submissions in minutes across tasksWhile this may not seem like a lot for some this was great for us We consider our workloads somewhat computationally expensive and didn t imagine we would get these sort of numbers out of our code Especially when hosting the server and database on the same machine Our logs indicated that we were on average consuming about of the CPU The data that we got was plenty for us to determine our hardware requirements but just for fun we decided to see how far we could push it We resized the VM to an Fs V vCPU GB expecting linear results The script was set concurrent tasks instead of to account for the increase in core count running for ten minutes The results total requests completed form submissions in minute across tasks What We doubled the hardware x d the number of concurrent runs and ended up with only more completed requests This set off an alarm for us we obviously had a large issue with the scalability of our application Investigating the IssueThe first thing that we theorized was that the increased number of tasks was causing problems with IIS causing connections to stay open for longer than they should We altered our the parameters of our test script to use tasks over minutes mirroring the test against the Fs machine After minutes the results were total requests completed form submissions in minutes across tasksThe same There was only a marginal difference in the results Less than from the original run The test machine was hardly using a fraction of the processing power and network it could utilize Something bigger was afoot We started a Remote Desktop session with the server and ran another test minutes cores We observed SQL Server start by consuming of our CPU time and watched it move up to as much as of the CPU by the end of the run Over time our performance was getting worse On a whim we ran a query to check for index fragmentation of the database The index fragmentation was far above what could be expected out of a healthy database North of for some indexes While we can t prove right now that this is what is causing our scaling issue it does explain how SQL server can continuously need more resources As the size of the data grows SQL is having to spend more time doing table scans and expending more resources on IO We found this puzzling we were using Entity Framework Core s Sequential Guid Value Generator With the DatabaseGeneratedOption Identity option The documentation states Generates sequential Guid values optimized for use in Microsoft SQL server clustered keys or indexes yielding better performance than random values This is the default generator for SQL Server Guid columns which are set to be generated on add It s important to note in addition to this documentation for those that aren t aware setting a column to use a GUID as a key with DatabaseGeneratedOption Identity does not mean that it will be generated by the database Instead EF Core generates the sequential GUID itself and then inserts it into the database read here This can be observed when comparing GUIDs generated normally to those generated by NEWSEQUENTIALID later in this post Additionally this issue in the EF core repository shows that EF core generates GUIDs better than SQL Server does The documentation wasn t lining up with what we were seeing it was time to recreate the EF tests and see if we could simulate the behavior we were getting from our server Running our Own BenchmarksThe first thing we did was see if we could reproduce the test done by roji on the EF core team with And MethodAverage page space used in Average fragmentation in percentRecord CountNEWSEQUENTIALID EF Core Sequential Guid Value Generator Same results as the team found The EF Core value generator is still generating GUIDs optimally as of SQL Server But wait this isn t really how a web server works Entities aren t just inserted one after another when coming from a web server Entries are created in response to user activity and that can happen whenever Database activity happens spontaneously whenever a user performs an action and different user hardware can mean these operations can take different amounts of time What if we modify the test instead to simulate a large degree of parallel actions rather than pure sequential inserts We altered our script instead of inserting sequential ids into the database we created tasks and told each of those tasks to insert rows into the database Once this was done we looked at index fragmentation again Parallel Entity Framework Sequential Guid Generationaverage page space used in average fragmentation in percentRecord Count

protected override void OnConfiguring DbContextOptionsBuilder optionsBuilder amp gt optionsBuilder UseSqlServer Server Database Testing Trusted Connection true Encrypt false public class Blog public Guid Id get set public string Name get set The top results returned when querying the database illuminate the issue Our conclusion Entity Framework seeks to create an efficient value generation strategy optimized for SQL Server but after the network stack has its say its likely that some rows will be inserted out of their original order Compare that to the results that you get when running the same code but setting HasDefaultValueSql NEWSEQUENTIALID in the OnModelCreating method in the database context Parallel Guid Generation with NEWSEQUENTIALID average page space used in average fragmentation in percentRecord Count The fragmentation percentage is still not as good as inserting the rows one after the other and the average page space used is a bit lower but I think we can all agree that it s better than generating the IDs in memory with Entity Framework Core This method has drawbacks too however Looking at the GUIDs that SQL generates it s hard to say that they have the same uniqueness guarantee that standard GUIDs have It appears that the leading bits of the GUIDs are all that change when taking a sample of the first inserted in the database after our concurrent test in case anyone is curious generating the GUIDs randomly led to a fragmentation percentage of almost Studying the IssueThere were two main benefits that initially brought us to use GUIDs as primary keys in our database We sometimes have to export data across servers so the near uniqueness guarantee meant that it should be trivial to merge the dataCertain actions don t require our users to be connected to our server all the time as long as they do a periodic sync In this case we could let the client generate IDs and after the sync turn the IDs into sequential ones Once we were done with the transformation we just had to inform the client of the new IDs Unfortunately the SQL server GUIDs don t seem like they would be able to cut it for us as it seems likely that a collision could occur when exporting from one server to another This led us to a tough crossroad Do weKeep going knowing that scaling up our application leads to highly diminishing returns necessitating expensive hardware ORLose the benefits GUIDs give us in favor of another primary key format that would be better suited for parallel inserts Ultimately we decided that our best path forward was to go with a hybrid approach We would alter our tables to have two IDs where GUIDs are required This involved using an integer primary key generated by the database and GUID value as a non clustered index with a unique constraint These GUIDs would use the SequentialGuidValueGenerator to try to presort some of the items in the non clustered index but we wouldn t enforce that it had to be a sequential GUID After performing our parallel benchmark we ended up with the following results Hybrid Key Generation Approachaverage page space used in average fragmentation in percentRecord Count Just in case we ran the benchmark again with only an integer primary key that yielded a fragmentation percentage of almost exactly It really just seems that some fragmentation is unavoidable in a parallel context The Great Key MigrationArmed with the results of the benchmarks we had ran we decided that we would make a gamble Every table that we had that used a GUID primary key we would alter to contain an auto incrementing integer primary key and a GUID UniqueId column with a unique constraint enforced We would still use the Entity Framework Core GUID value generator to create these unique Ids so to reduce the amount of work SQL would have to do maintaining the unique constraint In the end it took roughly two weeks of work and by the end we had modified files according to Git We ran the benchmark again with the new composite keys and our test script outputted the result total requests completed form submissions in minutes across tasksThis absolutely shocked us We had more than doubled our throughput obtaining a total boost of by changing our code to use integer primary keys instead of GUIDs Furthermore our core results showed a near linear increase of submissions and further analysis showed that the processor wasn t being utilized in this benchmark Some may say the time investment or the risk involved isn t worth it but in our minds the tradeoff we got was more than worth it ClosingI d like to end this post with a couple of acknowledgements First I don t believe that using the sequential id generator strategy is bad The Entity Framework Core team s benchmarks show that it does great work in a purely sequential workload As long as you aren t expecting a high degree of parallelism it seems that they are perfectly fine as a primary key Even if you do have a parallel workload its still possible to reorganize your clustered indexes Second I want to acknowledge that its totally possible that this is all a coincidence and that the GUIDs weren t the cause of the performance issues that we were seeing in SQL Server It s our belief that it s the culprit It s also of secondary importance for us to raise awareness that the assumption that we made that because SequentialGUidValueGenerator uses a strategy optimized for sequential access in SQL server that GUIDs aren t always going to be inserted sequentially Lastly I encourage anyone who reads this to look into the methods enclosed and run their own benchmarks to draw their own conclusions If there is a flaw in my methods I m happy to make an edit or publish a correction Thank You Thank you for reading my first blog post please let me know what worked and what didn t Conner It still perplexes us as to how it didn t show up on the smaller machine It s possible spoiler that since we had less cores we had a lesser degree of parallelism so rows were not being inserted out of order as bad	2023-03-24 16:15:57

海外TECH	Engadget	How to get your grill ready for the outdoor season	https://www.engadget.com/how-to-clean-your-grill-for-summer-outdoor-season-spring-cleaning-140040826.html?src=rss	How to get your grill ready for the outdoor seasonAs winter s chilly grip thaws it s time to spend our days on porches patios or in the backyard A key part of those warm weather activities is showing off your outdoor culinary skills to friends and family During the cold months your grill has likely been dormant so it s time to give it a thorough cleaning before it gets fired up several times a week Some of us keep the grill going year round but spring is a great time to do a deep clean before the official outdoor cooking season starts Here are a few tips and tricks that will hopefully make things easier Disassemble scrub reassembleBilly Steele EngadgetA good rule of thumb when it comes to cleaning anything you haven t used in a while is to take it apart as much as you feel comfortable and give it a thorough wipe down For grills this means removing the grates and any bars or burner covers basically anything you can take out that s not the heating element This gives you a chance to inspect the burners of your gas grill or the fire pot of a pellet model for any unsightly wear and tear If those components are worn out or overly rusted most companies offer replacements that you can easily swap out with a few basic tools Once all the pieces are out start by scraping excess debris off all sides of the interior with the help of some cleaner if needed For a gas grill this likely means pushing everything out through the grease trap On a pellet grill you ll want to scrape the grease chute clear and out into the catch can but you ll also need to vacuum the interior with a shop vac just like you would after every few hours of use And while you re at it go ahead and empty the hopper of any old pellets that have been sitting since labor day Fuel that s been sitting in the grill for months won t give you the best results when it comes time to cook so you might as well start fresh Thankfully pellet grill companies have made easy cleaning a key part of their designs Weber s SmokeFire has a set of metal bars on the inside that can be removed quickly to open up the bottom of the chamber This is also a design feature of the company s gas grills Simply vacuum or push the debris out the grease chute The catch pan where all of the garbage ends up is also easy to access from the front of the grill and you can remove the aluminum liner and replace it with a new one in seconds Traeger s most recent pellet grills were also redesigned to improve cleaning Most notably grease and ash end up in the same “keg that s easy to detach from the front of the grill The company also allows you to quickly remove all of the interior components though they re larger than what you find on the SmokeFire Lastly Traeger moved the pellet chute to the front of the new Timberline and Ironwood making it a lot more convenient to swap out wood varieties or empty an old supply You ll want to get as much of the food leftovers out of your grill as possible for a few reasons First that stuff is old and lots of build up over time can hinder cooking performance and might impact flavor The last thing you want is old food or grease burning off right under an expensive ribeye Second in the case of pellet grills not properly clearing out grease and dust can be dangerous It s easy for grease fires to start at searing temperatures and if there s enough pellet dust in the bottom of your grill it can actually ignite or explode That s why companies tell you to vacuum it out after every few hours of use All of that dust grease and debris should be removed before you fire the grill back up Billy Steele EngadgetTo actually clean the surfaces you ll want to get an all natural grill cleaner There are tons of options here and it may take some time to find one you like I typically use Traeger s formula since it s readily available at the places I buy pellets and I ve found it works well cutting through stuck on muck You want an all natural grill cleaner over a regular household product as it s safe to use on surfaces that will touch your food They re also safe to use on the exterior of your grill without doing any damage to chrome stainless steel or any other materials Spray down the inside and give things a few minutes to work Wipe it all clean and go back over any super dirty spots as needed Ditto for the grates bars and any other pieces you removed I like to lay these out on a yard waste trash bag they re bigger than kitchen bags so all the stuff I scrape or clean off doesn t get all over my deck You can use shop towels if you want to recycle or paper towels if not but just know whatever you choose will be covered in nasty black grime so you won t want to just toss them in the clothes washer when you re done A pre wash in a bucket or sink is needed to make sure you don t transfer gunk from your grill to your business casuals In terms of tools you don t need much I ve tried that grill robot that claims to do the job for you but I ve found sticking to the basics is more efficient And honestly when you get the hang of it it doesn t take all that long It s a good idea to have a wire brush specifically for the grates that you don t use to clean anything else After all this will be touching the same surfaces you put food on I recommend another smaller wire brush the ones that look like big toothbrushes for cleaning the burners on a gas grill If you notice the flame isn t firing through one of the holes you can use this to clean the pathway Lastly plastic is the way to go for a scraper anything else and you risk scratching the surfaces of your grill Sure any damage done would be on the inside but it s still not a great feeling to knick up your previous investment Check for updates before your first cookTraegerIf you have a smart grill from the likes of Traeger Weber or another company you ll want to plug it in and check for software updates well in advance of your first grilling session Chances are you haven t cooked much since last fall which means companies have had months to push updates to their devices Trust me there s nothing worse than spending an hour trimming and seasoning a brisket only to walk outside to start the grill and it immediately launches into the update process This could extend the whole cooking time significantly depending on the extent of the firmware additions and strength of your WiFi Thankfully checking for updates is quick and easy All you need to do is turn on your grill and open up the company s app on your phone If there s a download ready for your model the mobile software will let you know and it s usually quite prominent If there s not a pop up alert that displays immediately you can check the settings menu just to make sure Sometimes for smaller updates a company might not beat you over the head to refresh However starting a fresh slate of firmware is always a safe bet and will ensure your grill is running at its best when it comes time to cook For a good time every time clean after each useBilly Steele EngadgetI ll be the first to admit I don t adhere to my own advice here but it s nice to have goals I will also be the first to tell you every single time I smoke a Boston Butt or some other super fatty cut of meat that I wish I would ve done at least a quick cleaning right after the meal Grease buildup is not only highly flammable but it s much harder to clean once it cools and solidifies Ditto for stuck on sauce or cheese that s left on your grates after chicken or burgers It s best to attack these things while the grill is still warm but cooled down from the cook You don t necessarily have to break out the shop vac each time for your pellet grill or empty the grease bin But you ll want to make sure that stuff is away from the main cooking area for safety and so any burn

GCP	Cloud Blog	Kubernetes k8s.gcr.io redirect: what you need to know as an Anthos or GKE user	https://cloud.google.com/blog/products/containers-kubernetes/how-the-kubernetes-k8sgcrio-redirect-impacts-gke-and-anthos/	Kubernetes ks gcr io redirect what you need to know as an Anthos or GKE userIn November the open source Kubernetes project announced that its new image registry registry ks gcr io was officially GA The new registry would replace the legacy ks gcr io registry with ks gcr io getting no further updates after April To assist in this transition and ensure that users of earlier Kubernetes releases and tooling can update to supported versions in time the Kubernetes project in partnership with Google gradually started redirecting image requests from ks gcr io to registry ks io on March Today s post covers what s happening why and more importantly what actions you can take to switch to registry ks io to mitigate future issues Why is Kubernetes switching to the new registry Google open sourced the Kubernetes project and has supported the Cloud Native Computing Foundation CNCF since its inception Today there are millions of users and a massive global ecosystem of vendors and projects that support the project and the CNCF registry ks io the new vendor agnostic registry built by Kubernetes community members from Google Amazon VMware and elsewhere creates a global CDN for the project s container images spreading the load across multiple cloud providers This new registry is more sustainable for the project and provides a better experience for all Kubernetes users For additional information on the registry see the Kubernetes Community Blog post about its launch Why redirect requests The redirect is a temporary measure to smooth the transition to registry ks io Clusters should not continue to rely on ks gcr io in the long term the Kubernetes community plans to sunset it in the future The good news is that registry ks io is a mirror of ks gcr io that can be dropped in as a direct substitute for most users However if you use Google Kubernetes Engine GKE or Anthos in a restricted environment that applies strict domain name or IP address access policies such as with VPC Service Controls and you rely on Kubernetes community images from ks gcr io you may be impacted and need to make some adjustments to be future compatible What cluster configurations are impacted by the redirect Workloads that may be impacted are those that run on top of GKE and Anthos clusters running in a restricted environment that applies strict domain name or IP address access policies by using VPC Service Controls or other network access tooling Check for registry ks io connectivityTo test connectivity and image access to registry ks io run the following command code block StructValue u code u kubectl run hello world ti rm image registry ks io busybox latest restart Never date u language u u caption lt wagtail wagtailcore rich text RichText object at xeefef gt If the registry change doesn t affect you the output should look like the following code block StructValue u code u Fri Mar UTC r npod hello world deleted u language u u caption lt wagtail wagtailcore rich text RichText object at xeefef gt What kind of errors will I see if I m impacted You might notice an increase in ErrImagePull or ImagePullBackOff errors Container creation might fail with the warningFailedCreatePodSandBox for container images that reference ks gcr io The redirect doesn t affect running workloads You ll notice errors when scaling up the number of workloads or when creating new workloads that reference ks gcr io How can I detect what images in my cluster are impacted The Kubernetes community has devised the following methods Scan manifests and chartsIf you manage multiple clusters or don t have direct access to your clusters you can search your manifests and charts for ks gcr io This is the recommended method for larger or more complicated environments Use kubectlFind Pods that contain image references to ks gcr io code block StructValue u code u kubectl get pods all namespaces o jsonpath items spec containers image r ntr s space n r nsort r nuniq c r ngrep ks gcr io u language u u caption lt wagtail wagtailcore rich text RichText object at xeeddfd gt NOTE Direct updates to manifests might not change the references of some Pods returned by this command Pods that are controlled by system level services or by other controllers might require updating at the source before the effects can be seen Use a krew pluginUse community images a kubectl krew plugin that scans and generates a report of any Pods that run containers that reference ks gcr io If you have krew installed install the community images plugin code block StructValue u code u kubectl krew install community images u language u u caption lt wagtail wagtailcore rich text RichText object at xeecfd gt Then generate a report code block StructValue u code u kubectl community images u language u u caption lt wagtail wagtailcore rich text RichText object at xeee gt Other methods of installing the plugin are available in the kubernetes sigs community imagesGitHub repository NOTE Similarly to the kubectl method direct updates to manifests might not change the references of some Pods returned by this command Pods that are controlled by system level services or by other controllers might require updating at the source before the effects can be seen For additional options for detecting and blocking containers that contain references ks gcr io using third party tools see the Kubernetes Blog One of my workloads is impacted what should I do If you re using VPC Service Controls or if your environment is similarly restrictive add a rule to allow access to registry ks io If you can t add a rule the recommended forward compatible option is to mirror the affected images to a private instance of Artifact Registry by using gcrane and update your manifests to reference the image at its new location If you need other options or general assistance please reach out to Google Cloud support I m not affected by the redirect should I still update my image references Yes The redirect is temporary and the Kubernetes community plans to phase out support for ks gcr io in the future Getting helpIf you have questions or run into issues please check out the community resources available on this topic or contact us
