gianm opened a new pull request, #18765: URL: https://github.com/apache/druid/pull/18765
Since localSort was introduced for sort-merge join in #13506, it has used 1 processor at a time with a max of 2 channels per processor. This is inefficient, because at the time the sorter runs, it is the only sorter running. The patch contains a comment describing the situation in more detail. This patch has two benefits. First, the sorter should run faster if multiple processing threads are available. Second, the sorter, due to having a larger max channels per merger, will make more efficient use of intermediate channels. -- This is an automated message from the Apache Git Service.
