Subject [jira] [Commented] (HDFS-11580) Ozone: Support asynchronus client API for SCM and containers

    [ https://issues.apache.org/jira/browse/HDFS-11580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15973110#comment-15973110

Anu Engineer commented on HDFS-11580:
-------------------------------------

[~linyiqun] Thanks for the update. I was hoping that we would support the standard java 8
interface specified here. https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/CompletableFuture.html

A CompletableFuture future will allow us to write async code using standard java 8 patterns.

> This is an umbrella JIRA that needs to support a set of APIs in Asynchronous form.
> For containers -- or the datanode API currently supports a call {{sendCommand}}. we need
to build proper programming interface and support an async interface.
> There is also a set of SCM API that clients can call, it would be nice to support Async
interface for those too.
