Eugene Kirpichov created BEAM-4778: -------------------------------------- Summary: Less wasteful ArtifactStagingService Key: BEAM-4778 URL: https://issues.apache.org/jira/browse/BEAM-4778 Project: Beam Issue Type: Bug Components: runner-core Reporter: Eugene Kirpichov Assignee: Ryan Williams
[https://github.com/apache/beam/blob/master/runners/java-fn-execution/src/main/java/org/apache/beam/runners/fnexecution/artifact/BeamFileSystemArtifactStagingService.java] is the main implementation of ArtifactStagingService. It stages artifacts into a directory; and in practice the passed staging session token is such that the directory is different for every job. This leads to 2 issues: * It doesn't get cleaned up when the job finishes or even when the JobService shuts down, so we have disk space leaks if running a lot of jobs (e.g. a suite of ValidatesRunner tests) * We repeatedly re-stage the same artifacts. Instead, ideally, we should identify that some artifacts don't need to be staged - based on knowing their md5. The artifact staging protocol has rudimentary support for this but may need to be modified. CC: [~angoenka] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
