Marcus Eriksson created CASSANDRA-8301:
------------------------------------------
Summary: Create a tool that given a bunch of sstables creates a
"decent" sstable leveling
Key: CASSANDRA-8301
URL: https://issues.apache.org/jira/browse/CASSANDRA-8301
Project: Cassandra
Issue Type: Improvement
Reporter: Marcus Eriksson
In old versions of cassandra (i.e. not trunk/3.0), when bootstrapping a new
node, you will end up with a ton of files in L0 and it might be extremely
painful to get LCS to compact into a new leveling
We could probably exploit the fact that we have many non-overlapping sstables
in L0, and offline-bump those sstables into higher levels. It does not need to
be perfect, just get the majority of the data into L1+ without creating
overlaps.
So, suggestion is to create an offline tool that looks at the range each
sstable covers and tries to bump it as high as possible in the leveling.
