[GitHub] [bookkeeper] hangc0276 opened a new pull request #2643: adjust default rocksDbBlockCache size to 10%/numberOfLedgers of direct memory
hangc0276 opened a new pull request #2643:
URL: https://github.com/apache/bookkeeper/pull/2643
### Motivation
For dbLedgerStorage, it will initiate an RocksDB instance for each ledger directory. However, for each RocksDB instance, it will set defaultRocksDBBlockCacheSizeBytes to 10% of direct memory. If we configured multi ledger directories and default dbStorage_rocksDB_blockCacheSize, the direct memory will be exhausted and cause Out Of Memory Error(OOM)
### Changes
1. Change default dbStorage_rocksDB_blockCacheSize to 10% / numberOfLedgers of direct memory.
