> When using PCIe-SSD the flush speed will be really quick, and although we have per CF
flush, we still have the {{hbase.regionserver.optionalcacheflushinterval}} setting and some
other mechanism to avoid data kept in memory for too long to flush small hfiles. In our online
environment we found the single thread cleaner kept cleaning earlier flushed small files while
large files got no chance, which caused disk full then many other problems.
> Deleting hfiles in parallel with too many threads will also increase the workload of
namenode, so here we propose to separate large/small hfile cleaner threads just like we do
for compaction, and it turned out to work well in our cluster.
