Hi, We are thinking and planning to add proper multiplexing Async behaviour in jClouds. We plan to use the apache async httpClient library to achieve the same.
We are still thinking about how to implement this in jClouds and s3 proxy but below are are initial thoughts. 1. Move to Java 1.8 so we can start using CompletableFutures. (Let us know if you feel there are any issue in upgrading JAVA version) 2. Add a new annotation like @async which can be used in the client interfaces like AzureBlobClient.java, S3Client.java. 3. Add new methods for async in BlobStore and implement then in the specific stores. The methods will return completableFutures. 4. In the core http package add the apache async httpClient based class. Which will execute async http requests and return completable futures. (We are not sure if we can just add a implementation of BaseHttpCommandExecutorService.java for the same) 5. Make some changes in the DelegatesToInvocationFunction.java to see if async annotation is present and then using the Async client http executor. 6. The S3 proxy use jetty continuations to suspend the thread and then continue after the async method is done (using thenAccept in the Completable Future). Please do let me know your thoughts on this. Do you feel like this feature would be something useful for jClouds? Do you think we are on the right track on the way we plan to implement it? Any suggestions from your side?
