海外TECH	DEV Community	APIView vs Viewsets	https://dev.to/koladev/apiview-vs-viewsets-4ln0	APIView vs ViewsetsWhen building your API in Django using Django Rest Framework you have two choices for writing the controllers APIView or ViewSets APIViewAPIView provides a methods handler for HTTP verbs get post put patch and delete But you ll need to write a method for each HTTP verb For example you are writing a view for a Product resources with a ProductSerializer Here s an example of the View with a get method to return all the products in the database from rest framework views import APIViewclass ProductView APIView serializer class ProductSerializer def get self request args kwargs products Product objects all serializer self serializer class products many True return Response serializer data APIView works best for simple endpoints that won t really require many possibles HTTP requests What do I mean Suppose that you want an endpoint to create a product Pretty simple We can quickly handle it from rest framework views import APIViewclass ProductView APIView serializer class ProductSerializer def get self request args kwargs products Product objects all serializer self serializer class products many True return Response serializer data def post self request args kwargs serializer self serializer class data request data serializer is valid raise exception True return Response serializer data We can now create a product but let s suppose we want to make a certain action on the product like make it unavailable To do it a POST request must be sent to the endpoint and we ll handle the rest with some methods on the Product model We can t do that in the ProductView class because there is already a post method A solution Add another APIView and this starts becoming quite verbose Not to add that you ll have to add two different URL routes for the same resource which can be a bad API design A solution ViewSets ViewSetsA ViewSet is a class based view able to handle all of the basic HTTP requests GET POST PUT DELETE without hard coding any of the logic The viewsets module also provides a ModelViewSet class that maps HTTP request actions to CRUD actions in the Database For example let s rewrite the ProductView in a ModelViewSet class ProductViewSet ModelViewSet queryset Product objects all serializer class ProductSerializer http method names get post Well this is doing the same job as the ProductView Interesting right This is even more interesting when we want a certain action on the same resource no need to add a new class class ProductViewSet ModelViewSet action detail True methods post def unavailable self request args kwargs obj self get object obj unavailable return Response status unavailable And that s not all If you are working with viewsets instead of URL you ll be working with routers And here s how to register a viewsets in your router file router routers DefaultRouter router register r products ProductViewSet And with this you ll have the following structure for the products endpoint EndpointHTTP MethodDescription products POSTCreating a new product products GETGet the list of all users products product id GETRetrieve a product products product id unavailable POSTMake a product unavailable SummaryAPIView and ViewSet all have their right use cases But most of the time if you are only doing CRUD on resources you can directly use ViewSets to respect the DRY principle But if you are looking for more complex features you can go low level because after all viewsets are also a subclass of APIView More on viewsets and views Article posted using bloggu io Try it for free	2022-04-04 08:22:42

海外TECH	DEV Community	Google Cloud Functions 2nd gen	https://dev.to/zenika/google-cloud-functions-2nd-gen-d0m	Google Cloud Functions nd genGoogle has just released in beta the second generation of Google Cloud Functions For those who are not yet familiar with Google Cloud Functions you can read my article Quarkus and Google Cloud Functions This second generation brings A longer maximum processing time mn instead of mn Instances up to GB vCPU instead of GB vCPU The ability to have instances always available Better concurrency management up to concurrent calls per instance CloudEvents support via EventArc more than events available All the new features of Cloud Functions gen are available here Icing on the cake Quarkus is already ready for them I have had access to the private alpha version so I already made the Quarkus extension compatible In this article I will talk about to the two points that seem to me the most interesting ones better concurrency and support for CloudEvents Deployment and first callFirst let s deploy the same function in the st gen and nd gen runtimes I will use the HTTP function from the Quarkus extension integration test for Google Cloud Functions available here First thing to do package the function via mvn clean package Quarkus will generate an uber jar in the target deployment directory which we will then use to deploy our function To deploy the function in the st gen runtime gcloud functions deploy quarkus example http v entry point io quarkus gcp functions QuarkusHttpFunction runtime java trigger http source target deploymentThe build is done via Cloud Build and takes about s After deployment I make a first call to the function via curl then I access its logs to see the function startup time and the time of the first call D quarkus example http v bzhewod Function execution took ms finished with status code D quarkus example http v bzhewod Function execution started quarkus example http v INFO oejs Server main Started ms I quarkus example http v Installed features cdi google cloud functions I quarkus example http v Profile prod activated I quarkus example http v quarkus integration test google cloud functions SNAPSHOT on JVM powered by Quarkus SNAPSHOT started in s I quarkus example http v JBoss Threads version Final quarkus example http v INFO main Logging initialized ms to org eclipse jetty util log StdErrLog quarkus example http v Picked up JAVA TOOL OPTIONS XX MaxRAM m XX MaxRAMPercentage We note that the function started in s including s for starting Quarkus The first call took ms Let s do the same for the nd gen runtime for which we can deploy the same function with gcloud beta functions deploy quarkus example http v entry point io quarkus gcp functions QuarkusHttpFunction runtime java trigger http source target deployment genThe build is done via Cloud Build and takes about s After deployment I make a first call to the function via curl and then I immediately notice that the call is very very long I access its logs to see the function startup time and the time of the first call I quarkus example http v quarkus example http v INFO oejs Server main Started ms I quarkus example http v Installed features cdi google cloud functions I quarkus example http v Profile prod activated I quarkus example http v quarkus integration test google cloud functions SNAPSHOT on JVM powered by Quarkus SNAPSHOT started in s I quarkus example http v JBoss Threads version Final gt OTHER STARTING LOGS lt Several observations the start up time is much longer around s including s for Quarkus we find the same ratio start up runtime vs Quarkus one but times more Also the curl call just after the deployment triggers another function startup Successive calls will be much faster There is a very different behavior here between generations and I will contact the Google team on the subject for investigation Better concurrencyTo compare the concurrency management I will simulate a heavy load with the tool wrk on both runtimes On each runtime I perform two successive tests one over minute with threads for connections and another over minutes with threads for connections wrk c t d latency https my function host quarkus example http vwrk c t d latency https my function host quarkus example http vHere are the results for the st gen runtime threads and connections Thread Stats Avg Stdev Max Stdev Latency ms ms s Req Sec Latency Distribution ms ms ms ms requests in m MB read Socket errors connect read write timeout Requests sec Transfer sec KB threads and connections Thread Stats Avg Stdev Max Stdev Latency ms ms s Req Sec Latency Distribution ms ms ms ms requests in m MB read Socket errors connect read write timeout Non xx or xx responses Requests sec Transfer sec KBAnd here are the results for the nd gen runtime threads and connections Thread Stats Avg Stdev Max Stdev Latency ms ms s Req Sec Latency Distribution ms ms ms ms requests in m MB read Socket errors connect read write timeout Non xx or xx responses Requests sec Transfer sec KB threads and connections Thread Stats Avg Stdev Max Stdev Latency ms ms s Req Sec Latency Distribution ms ms ms ms requests in m MB read Socket errors connect read write timeout Non xx or xx responses Requests sec Transfer sec KBThe average performance is similar for the two runtimes with a slightly lower average time for the nd gen When we look in detail at the latency tail latency we notice a more marked difference for the nd gen which has a much lower latency especially during the first load test ms versus ms We can clearly see the interest of increased concurrency for nd gen functions more requests processed per instance equals fewer function startups and therefore fewer cold starts We can validate this by looking at the number of instances started via the Google Cloud console and we see that there are about half as many instances started in nd gen as in st gen to instances versus to instances st gen Nb instances nd gen Nb instances CloudEventsOne of the most exciting nd gen functionality is the ability to create functions of Cloud Events type These are event functions that instead of receiving an event in a proprietary Google Cloud format will receive one in a standard format as described in the Cloud Events specification Here is an example of a cloud function receiving an event of type Storage and using the proprietary Google Cloud event it s a background function that uses a proprietary StorageEvent event object public class BackgroundFunctionStorageTest implements BackgroundFunction lt StorageEvent gt Override public void accept StorageEvent event Context context throws Exception System out println Receive event on file event name public static class StorageEvent public String name To deploy this function and make it listen on an event on the quarkus hello bucket we can use the following command gcloud functions deploy quarkus example storage entry point com example BackgroundFunctionStorageTest trigger resource quarkus hello trigger event google storage object finalize runtime java source target deploymentHere is an example of a cloud function receiving a standard event of type CloudEvents it uses the Java CloudEvents library which provides the CloudEvent object public class CloudEventStorageTest implements CloudEventsFunction Override public void accept CloudEvent cloudEvent throws Exception System out println Receive event Id cloudEvent getId System out println Receive event Subject cloudEvent getSubject System out println Receive event Type cloudEvent getType System out println Receive event Data new String cloudEvent getData toBytes It is at deployment time of this function that we will specify that the trigger will be on a Storage type event by specifying the bucket gcloud beta functions deploy quarkus example cloud event gen entry point com example CloudEventsFunctionStoragetTest runtime java trigger bucket example cloud event source target deploymentThe content of the Storage event will be in the data attribute of the CloudEvent object ConclusionEven if the nd gen is still in preview the advantage offered in terms of performance and cold start alone makes it worth starting to use it even if it remains to solve the issue of the first function startup which take a lot of time Moreover support for the CloudEvents standard makes it possible to write functions that are less dependent on Google Cloud and above all to use a format that is supported on other clouds and in other technologies Kafka broker HTTP client	2022-04-04 08:19:11
