海外TECH	DEV Community	type vs interface in TypeScript	https://dev.to/saadsharfuddin/type-vs-interface-in-typescript-35i6	type vs interface in TypeScriptWhen I first started working with TypeScript I quickly found myself questioning the use of type and interface in regards to providing type safety to my code What is the difference between the two When should I use one over the other I decided it was time to get some answers After a bit of research I realized that the two are more similar today than they have ever been However there are still some differences that are worth mentioning Let s talk about it types and interfaces at a high levelBefore we take a look at the similarities and differences between a type and an interface let s first get a good mental model of what the two were intended to achieve in the first place The type keyword in TypeScript is a way for you to provide type aliases to your variables objects and functions These aliases essentially describe what your data is going to look like You can describe what your data is going to look like by using the core types e g string number boolean etc or by creating your own custom types Let s take a look at a few examples The interface keyword in TypeScript on the other hand is a way for you to describe only what your objects are going to look like Let s see an example of interface Right off the bat you might think that the type keyword is the more flexible choice of the two when it comes to type safety Hold that thought Let s take a look now at how the two are similar SimilaritiesLet s say I wanted to provide some type safety for an object one of the most common use cases for using a type or an interface Turns out they both work pretty much the same and the syntax is almost identical What if I wanted to combine object properties from one type or interface into another We can do that too for both I personally prefer the extends syntax as it feels a bit more natural to me Want to provide some type safety to your functions This is also possible with both a type and an interface I personally prefer using a type here since it reads a bit cleaner but totally up to you A quick note about the above Earlier I mentioned that an interface can only describe what an object is going to look like yet here I am describing what a function is going to look like with an interface The reason this is possible is because a function technically is an object under the hood Finally if you wanted to create a class that adheres to a certain type safety contract provided by a type or an interface you would be able to do so just fine with both That covers most of the similarities of type and interface let s now take a look at the differences DifferencesStarting with type there are a few things that are possible that you wouldn t be able to do with an interface For example If you wanted to setup a type alias for just a single core type e g string number boolean etc this is something that is possible with type but not with interface Another possibility with type is that you are able to create a bit more custom type aliases by using unions This pretty much sums up the unique offerings of type While there may be some more advance features that type offers that I missed this should cover the most common use cases Moving on to interface there is a unique feature called “declaration merging that you aren t able to do with a type Wrapping upTo summarize both type and interface provide some nice type safety options for you to choose from depending on your needs When it comes to describing object shapes which is the majority of my use cases I prefer to go with an interface I personally like that an interface was designed specifically with this purpose in mind and is very intentional about it However anytime I need to provide type safety for a function or need a bit more customization for a type alias such as the case with unions I prefer to go with type Both are lovely options for providing type safety and you really can t go wrong with using either one	2021-04-09 19:10:17

GCP	Cloud Blog	Lighter lift-and-shifts with the new Database Migration Service	https://cloud.google.com/blog/topics/developers-practitioners/lighter-lift-and-shifts-new-database-migration-service/	Lighter lift and shifts with the new Database Migration Service“Database migrations are super fun No one ever There can be considerable friction in moving databases from platform to platform If you re doing a lift and shift to Google Cloud your ability to take advantage of cloud features slows down when you have to handle all the intricacies of Devising a migration strategy for safely and efficiently moving data while managing downtime Assessing the impact of the migrationDatabase preparationSecure connectivity setupData replicationAnd migration validationBeyond that there might be manual work to rewrite database code for a new engine or rewrite applications and deep validation of aspects like performance impact It goes without saying that migration to the cloud is a complex process with many moving parts and personas involved including a network administrator to account for infrastructure security requirements like VPN Most DBAs know that one of the largest risks of migrating a database is downtime which often prevents companies from taking on the heavy task Typically you shutdown the application create a backup of the current database schema perform all required update operations using migration tools restart the application and hope that everything works fine  But that changes if you can t accept any downtime PostgreSQL users for example often have very large databases meaning they are facing hours of downtime which for most companies isn t realistic  Migration tools as a fast trackA number of tools are available to help you move data from one type of database to another or to move data to another destination like a data warehouse or data lake Moving critical datasets ーentire databases ーrequires the latest generation cloud based migration tools that can handle data replication with ease while providing enhanced security While we ve seen cloud based migration tools like Alooma Matillion and Snaplogic we also know cloud migration tools need to integrate well with both the source and the target systems enabling you to migrate databases with minimal effort downtime and overhead  In Alooma joined Google Cloud bringing Alooma one step closer to delivering a full self service database migration experience bolstered by Google Cloud technology Alooma helps enterprise companies streamline database migration in the cloud with a data pipeline tool that simplifies moving data from multiple sources to a single data warehouse The addition of Alooma and their expertise in enterprise and open source databases has been critical to bringing additional migration capabilities to Google Cloud Then in November Google Cloud launched the new serverless Database Migration Service DMS as part of our vision for meeting these modern needs in a user friendly fast and reliable way for migration to Cloud SQL While Alooma is an ETL platform for data engineers to build a flexible streaming data pipeline to a cloud data warehouse for analytics DMS is a database migration service for DBAs and IT professionals to migrate their databases to the cloud as part of their larger migration goals Database Migration Service is now GADatabase Migration Service makes it easy for you to migrate your data to Google Cloud It s a fully managed service that helps you lift and shift your MySQL and PostgreSQL workloads into Cloud SQL You can migrate from on premises self hosted in Google Cloud or from another cloud and get a direct path to unlocking the benefits of Cloud SQL The focus of DMS is to manage the migration of your database schema metadata and the data itself It streamlines the networking workflow manages the initial snapshot and ongoing replication provides a status of the migration operation and supports one time and continuous migrations This lets you cut over with minimal downtime  That s a lot to absorb but here are three main things I want you to take away  With DMS you get a simple integrated experience to guide you through every step of the migration not just a combination of tools to perform the assessment and migration It s serverless You don t need to deploy manage or monitor instances that run the migration The onus of deciding on appropriate sizing monitoring the instance ensuring that compute storage are sufficient is on Google Cloud Serverless migrations eliminate surprises and are performant at scale It s free Supported source databases include AWS RDS Self managed on prem on any cloud VM Cloud SQL Supported destination databases include Cloud SQL for MySQL Gabe Weiss Developer Advocate for Cloud SQL has gone in depth around the various migration scenarios how DMS works and how to prepare Postgres instances for migration so check out his content as well as best practices around homogeneous migrations For now I ll give you a quick sneak peak by walking you through the basic DMS experience for a new migration job A stroll through DMSGabe WeissYou can access DMS from the Google Cloud console under Databases To get started you ll create a migration job This represents the end to end process of moving your source database to a Cloud SQL destination  Define your migration jobFirst let s define what kind of migration the job will run I want to move a MySQL database I am running on Google Compute Engine to Cloud SQL I can choose between one time or a continuous replication For minimal downtime I select continuous Once I define my job DMS shows me the source and connectivity configuration required to be able to connect to and migrate the source database DMS clearly explains what you need to do by showing you the prerequisites directly in the UI   Don t skip this step Be sure to review these prerequisites because you re going to save yourself a headache during connectivity testing  Define your sourceFirst you have to create a connection profile a resource that represents the information needed to connect to a database These profiles aren t locked to an individual migration This means you can reuse it if you want to first test out a migration or if someone else in your organization is in charge of connecting to the database  If you re replicating from a self hosted database enter the Hostname or IP address domain or IP and Port to access the host  If you re replicating from a Cloud SQL database select the Cloud SQL instance from the dropdown list Create a destinationThe next step is to create the Cloud SQL instance to migrate the database to This will feel familiar to anyone who has created a Cloud SQL instance before You ll see many of the same options like connectivity and machine configuration Since DMS relies on the replication technology of the Database Engine you don t have to create resources aside from the Cloud SQL instance Connect your source to your target To me this is where the magic is because establishing connectivity is often viewed as pretty hard Depending on the type of your source database and its location you can choose among four types of connectivity methods IP allowlists Use this when your source database is external to Google Cloud Reverse SSH tunnel Use this to set up private connectivity through a reverse SSH tunnel on a VM in your project VPCs through VPNs Use this if your source database is inside a VPN i e in AWS or your on premises VPN VPC peering Use this if your source database is in the same VPC on Google Cloud Since my source VM is in Google Cloud I set up VPC Peering Just be sure to enable the Service Networking API to do this which provides automatic management of network configurations necessary for certain services Validate the migration jobAnd that s it I configured my source created a Cloud SQL destination and established connectivity between them All that s left is to validate the migration job setup and start my migration Once it s validated I can trust that my migration will run smoothly You can start the job and run it immediately Once the migration job has started you can monitor its progress and see if it encounters any issues DMS will first transfer the initial snapshot of existing data then continuously replicate changes as they happen  When the initial snapshot is migrated and continuous replication is keeping up you can promote the Cloud SQL instance to be your primary instance and point your applications to work directly against it DMS guides you through the process and manages the connection between your source and Cloud SQL instance with flexible options You can test the migration and get a reliable way to migrate with minimal downtime to a managed Cloud SQL instance It s serverless highly performant and free to use If you want to give it a spin check out the quickstart and migrations solutions guide and let me know your thoughts and any feedback  Looking for SQL Server migrations You can request access to participate in the SQL Server preview Find me on Twitter   stephr wong	2021-04-09 19:30:00
