Paulo Motta commented on CASSANDRA-10680: ----------------------------------------- Patch and tests look good. Thanks! > Deal with small compression chunk size better during streaming plan setup > ------------------------------------------------------------------------- > > Key: CASSANDRA-10680 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10680 > Project: Cassandra > Issue Type: Bug > Reporter: Jeff Jirsa > Assignee: Yuki Morishita > Fix For: 3.0.1, 3.1, 2.1.x, 2.2.x > > > For clusters using small compression chunk size and terabytes of data, the > streaming plan calculations will instantiate hundreds of millions of > compressionmetadata$chunk objects, which will create unreasonable amounts of > heap pressure. Rather than instantiating all of those at once, streaming > should instantiate only as many as needed for a single file per table at a > time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
