> Write Ahead Log Batching Optimization

> The new write ahead log mechanism seems to batch too few mutations when
> running inside the disruptor. As we scaled our load up (many threads with
> small writes), we saw the number of hdfs sync operations grow in concert with
> the number of writes. Generally, one would expect the size of the batches to
> grow but the number of actual sync operations to settle.
