[jira] [Created] (ACCUMULO-1055) Configurable maximum size in which
to perform merging minor compactions
Josh Elser created ACCUMULO-1055:
------------------------------------
Summary: Configurable maximum size in which to perform merging minor compactions
Key: ACCUMULO-1055
URL: https://issues.apache.org/jira/browse/ACCUMULO-1055
Project: Accumulo
Issue Type: Improvement
Components: tserver
Reporter: Josh Elser
Assignee: Keith Turner
When performing a merging minor compaction, the smallest file for a tablet is chosen, and then data to be minor compacted is merged with said small file.
When the smallest file isn't actually small, this can cause extremely large/long minor compactions. I don't want to completely "disable" merging minor compactions, for as I continue to run ingest, I'd like to take advantage of merging the small files together via minc.
An upper bound on the file size to merge seems the most straightforward means to control this.
