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) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
