Jian Zhang updated HDFS-17552: ------------------------------ Attachment: HDFS-17552.patch Status: Patch Available (was: Open) > [ARR] RPC client uses CompletableFuture to support asynchronous operations. > --------------------------------------------------------------------------- > > Key: HDFS-17552 > URL: https://issues.apache.org/jira/browse/HDFS-17552 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Jian Zhang > Assignee: Jian Zhang > Priority: Major > Labels: pull-request-available > Attachments: HDFS-17552.patch > > > h3. Description > In the implementation of asynchronous Rpc.client, the main methods used > include HADOOP-13226, HDFS-10224, etc. > However, the existing implementation does not support `CompletableFuture`; > instead, it relies on setting up callbacks, which can lead to the "callback > hell" problem. Using `CompletableFuture` can better organize asynchronous > callbacks. Therefore, on the basis of the existing implementation, by using > `CompletableFuture`, once the `client.call` is completed, the asynchronous > thread handles the response of this call without blocking the main thread. > > *Test* > new UT TestAsyncIPC#testAsyncCallWithCompletableFuture() -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
