wangningito created KUDU-3214: --------------------------------- Summary: Parallelize DownloadWAL in tablet copy operations Key: KUDU-3214 URL: https://issues.apache.org/jira/browse/KUDU-3214 Project: Kudu Issue Type: New Feature Components: consensus, tablet Reporter: wangningito Assignee: wangningito
When downloading tablet data via tablet copy operation, it is necessary to download blocks data and wal data. In [KUDU-1728|https://issues.apache.org/jira/browse/KUDU-1728] the DownloadBlocks were parallelized. However, to intuition, it may make senses to make DownloadWALs parallelized as well. It requires very strict performance tests and correctness guarantee to determine whether to have parallelized version DownloadWALs or not. -- This message was sent by Atlassian Jira (v8.3.4#803005)
