---------------------------------------
Summary: Add user defined SSTables option for nodetool
garbagecollect
Key: CASSANDRA-16767
URL: https://issues.apache.org/jira/browse/CASSANDRA-16767
Project: Cassandra
Issue Type: Improvement
Reporter: Scott Carey
Assignee: Scott Carey
nodetool garbagecollect does not yet have an option to supply a user defined
list of SSTables to process.
This is unfortunate, because there are many cases where an operator would know
which subset of tables are in need of a garbagecollect. Perhaps with STCS, one
would choose to garbagecollect only the largest file.
With a large LCS table, it is typical that the highest levels have the most
overwritten data, and it may take a very long time to run a full
garbagecollect or full compaction, but a relatively short time to process a
smaller subset of SSTables.
