Summary: Dynamic Table TTL Key: CASSANDRA-17372 URL: https://issues.apache.org/jira/browse/CASSANDRA-17372 Project: Cassandra Issue Type: Improvement Components: CQL/Semantics Reporter: Paulo Motta One limitation of the {{default_time_to_live}} option is that it only applies to newly inserted data so an expensive migration is required when altering the table-level TTL, which is not an uncommon request due to changes in retention policies. This seems to have been a deliberate design decision when adding the Table TTL feature on CASSANDRA-3974, due to the reasons stated [on this comment|https://issues.apache.org/jira/browse/CASSANDRA-3974?focusedCommentId=13427314&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-13427314] so we should revisit and potentially address these concerns. I would like to explore supporting dynamic TTL, which would reflect any updates to the table-level {{default_time_to_live}} immediately to all table data. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
