Lars Hofhansl created HBASE-10247: ------------------------------------- Summary: Client promises about timestamps Key: HBASE-10247 URL: https://issues.apache.org/jira/browse/HBASE-10247 Project: HBase Issue Type: Brainstorming Reporter: Lars Hofhansl Priority: Minor
This is to start a discussion about timestamp promises declared per table of CF. For example if a client promises only monotonically increasing timestamps (or no custom set timestamps) and VERSIONS=1, we can aggressively and easily remove old versions of the same row/fam/col from the memstore before we flush, just by supplying a comparator that ignores the timestamp (i.e. two KV just differing by TS would be considered equal). That would increase the performance of counters significantly. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
