-------------------------------------------
Summary: Make DTCS work well with old data
Key: CASSANDRA-10280
URL: https://issues.apache.org/jira/browse/CASSANDRA-10280
Project: Cassandra
Issue Type: Sub-task
Reporter: Marcus Eriksson
Assignee: Marcus Eriksson
Fix For: 3.x, 2.1.x, 2.2.x
Operational tasks become incredibly expensive if you keep around a long
timespan of data with DTCS - with default settings and 1 year of data, the
oldest window covers about 180 days. Bootstrapping a node with vnodes with this
data layout will force cassandra to compact very many sstables in this window.
We should probably put a cap on how big the biggest windows can get. We could
probably default this to something sane based on max_sstable_age (ie, say we
can reasonably handle 1000 sstables per node, then we can make calculate how
big the windows should be to allow that)
