   15:16:23.548 [BookieWriteThreadPool-OrderedExecutor-0-0] INFO  org.apache.bookkeeper.bookie.storage.ldb.DbLedgerStorage - Write cache is full, triggering flush
   ```
   Regarding this log, we could try to set these vars.
   
   ```
   # Size of Write Cache. Memory is allocated from JVM direct memory.
   # Write cache is used to buffer entries before flushing into the entry log
   # For good performance, it should be big enough to hold a substantial amount
   # of entries in the flush interval
   #  By default it will be allocated to 1/4th of the available direct memory
   dbStorage_writeCacheMaxSizeMb=
   
   # Size of Read cache. Memory is allocated from JVM direct memory.
   # This read cache is pre-filled doing read-ahead whenever a cache miss happens
   #  By default it will be allocated to 1/4th of the available direct memory
   dbStorage_readAheadCacheMaxSizeMb=
   ```
