> A colleague of mine ran into an interesting issue.
> He inserted some data with the WAL disabled, which happened to fit in the
> aggregate Memstores memory.
> Two weeks later he a had problem with the HDFS cluster, which caused the
> region servers to abort. He found that his data was lost. Looking at the log
> we found that the Memstores were not flushed at all during these two weeks.
> Should we have an option to flush memstores periodically. There are obvious
> downsides to this, like many small storefiles, etc.
