yzang opened a new pull request #513: BOOKKEEPER-1106: Introduce write FileInfo cache and read FileInfo cache URL: https://github.com/apache/bookkeeper/pull/513 Problem: when read behind happens, it would quickly read bunch of ledgers, which will evict current active ledgers for writing from the ledger cache. with the ledger being evicted from cache, it would impact the write performance. This feature is contributed by @sijie , in which we introduced write file info cache and read file info cache to cache the ledger index separately for read and write, so that when catch up read happens, it will not evict the file info for writes. > --- > Be sure to do all of the following to help us incorporate your contribution > quickly and easily: > > - [ ] Make sure the PR title is formatted like: > `<Issue # or BOOKKEEPER-#>: Description of pull request` > `e.g. Issue 123: Description ...` > `e.g. BOOKKEEPER-1234: Description ...` > - [ ] Make sure tests pass via `mvn clean apache-rat:check install findbugs:check`. > - [ ] Replace `<Issue # or BOOKKEEPER-#>` in the title with the actual Issue/JIRA number. > > --- ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
