Jian Zhang created HDFS-17552: --------------------------------- Summary: [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
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
