[jira] [Created] (HBASE-27324) Auto merging small stripes in StripeCompactionPolicy

Xiaolin Ha created HBASE-27324:
----------------------------------

             Summary: Auto merging small stripes in StripeCompactionPolicy
                 Key: HBASE-27324
                 URL: https://issues.apache.org/jira/browse/HBASE-27324
             Project: HBase
          Issue Type: Improvement
          Components: Compaction
    Affects Versions: 2.4.13, 3.0.0-alpha-3
            Reporter: Xiaolin Ha
             Fix For: 2.6.0, 3.0.0-alpha-4


Currently, stripes merge only happens when two stripes are empty, but that is not enough. With the data appending the stripes splits by splits, but with the data deleting, stripes might become smaller size while the stripes count is large. 

Auto merging small stripes can help to reduce the file count in the store and improve read effiecency.
