-------------------------------------
Summary: flush the METADATA table after GC
Key: ACCUMULO-1281
URL: https://issues.apache.org/jira/browse/ACCUMULO-1281
Project: Accumulo
Issue Type: Improvement
Components: gc
Reporter: Eric Newton
Assignee: Eric Newton
Priority: Trivial
Fix For: 1.5.0
The METADATA table is often small, with many in-memory writes. Because it is
small, it does not normally get flushed, which will prune data with the
versioning/delete iterators. Over time, the many in-memory versions can cause
poor performance.
The file garbage collector (gc) will make lots of updates as it runs. That
would be a perfect time to flush the table and prune the versions.
