Apache HBase Configurations
Apache HBase supports built-in mechanisms to handle region splits and compactions. Split/compaction storms can occur when multiple regions grow at roughly the same rate, and eventually split at about the same time. This can cause a large spike in disk I/O because of the compactions needed to rewrite the split regions.
Tip
Rather than relying on Apache HBase to automatically split and compact the growing regions, you can perform these tasks manually.
If you handle the splits and compactions manually, you can perform them in a time-controlled manner and stagger them across all regions to spread the I/O load as much as possible to avoid potential split/compaction storms. With the manual option, you can further alleviate any problematic split/compaction storms and gain additional performance.
