freemandealer opened a new pull request, #51776:
URL: https://github.com/apache/doris/pull/51776
this pr does the following:
1. make file cache downloader worker pool thread num configurable
2. make warm up job split batch size configurable
3. split large file downloading task to smaller ones to maintain load
balance between threads, thus improve concurrency
4. use meta info to deduce size of inverted idx file size to reduce S3 HEAD
ops
5. some log print optimization
in our test, this opt can improve more than 3x file cache warm up performance
