Wouldn't be better to use TimeWindowCompactionStrategy as compaction strategy for newts (at least the samples table), in most scenarios the old data (more than a week ago), is hardly in need, but it's load on compaction should be tolerated for a year (Hundred of gigabytes compaction that would took Hours and slow down reads), Using TWCS, each week's data would be compacted in a single isolated SSTable, and won't be annoying for a year (after that would be deleted by TTl with the least load on system) P.S: TWCS is the recommended strategy for Time series by DataStax Sent using Zoho Mail _______________________________________________ Please read the OpenNMS Mailing List FAQ: http://www.opennms.org/index.php/Mailing_List_FAQ opennms-discuss mailing list To *unsubscribe* or change your subscription options, see the bottom of this page: https://lists.sourceforge.net/lists/listinfo/opennms-discuss
