[PR] [CELEBORN-2194] Change default value of celeborn.worker.directMemoryRatioForReadBuffer [celeborn]
SteNicholas opened a new pull request, #3527:
URL: https://github.com/apache/celeborn/pull/3527
### What changes were proposed in this pull request?
Change default value of `celeborn.worker.directMemoryRatioForReadBuffer` from 0.1 to 0.35.
### Why are the changes needed?
The default value of `celeborn.worker.directMemoryRatioForReadBuffer` is 0.1, which is too small to cause a backlog of read buffer requests in `ReadBufferDispacther`. Therefore, `celeborn.worker.directMemoryRatioForReadBuffer` should be changed from `0.1` to `0.35` to raise read buffer threshold of `ReadBufferDispatcher`.
### Does this PR resolve a correctness bug?
No.
### Does this PR introduce _any_ user-facing change?
The default value of `celeborn.worker.directMemoryRatioForReadBuffer` is changed to 0.35.
### How was this patch tested?
CI.
