Liya Fan created ARROW-11901: -------------------------------- Summary: [Java] Investigate potential performance improvement of compression codec Key: ARROW-11901 URL: https://issues.apache.org/jira/browse/ARROW-11901 Project: Apache Arrow Issue Type: Improvement Components: Java Reporter: Liya Fan Assignee: Liya Fan
In response to the discussion in https://github.com/apache/arrow/pull/8949/files#r588046787 There are some performance penalties in the implementation of the compression codecs (e.g. data copying between heap/off-heap data). We need to revise the code to improve the performance. We should also provide some benchmarks to validate that the performance actually improves. -- This message was sent by Atlassian Jira (v8.3.4#803005)
