public RocksDbTableDescriptor<K, V> withWriteBufferSize(int writeBufferSize) {
    this.writeBufferSize = writeBufferSize;
    return this;
  }
The amount of memory (in bytes) that RocksDB uses for buffering writes before they are
written to disk, per container. If there are several task instances within one container,
each is given a proportional share of this buffer. This setting also determines the
size of RocksDB's segment files.
<p>
Default value is 33,554,432.
