------------------------------------
Summary: Periodically flush the Memstore?
Key: HBASE-5930
URL: https://issues.apache.org/jira/browse/HBASE-5930
Project: HBase
Issue Type: Improvement
Reporter: Lars Hofhansl
Priority: Minor
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.
