Sean Busbey commented on HBASE-13023:
-------------------------------------

MultiWAL allows a RegionServer to write multiple WAL streams in parallel, based
upon the number of write replicas HDFS uses, and increase total throughput
during the writes.
{quote}
I'd rephrase as "MultiWAL allows a RegionServer to write multiple WAL streams
in parallel, by using multiple pipelines in the underlying HDFS instance, which
increases total throughput during writes. Note that this parallelization is
done by partitioning incoming edits by their Region. Thus, the current
implementation will not help with increasing the throughput to a single Region."
