Lars Hofhansl commented on PHOENIX-5592: ---------------------------------------- Thanks [~yanxinyi]. We just need to carefully consider any standard (or broadly available) feature that requires running periodic M/R jobs to function. I think I remember discussions I had with [~jisaac] about this. This is when we want to drop expired rows/views immediately, right? We'll check in next year. > MapReduce job to asynchronously delete rows where the VIEW_TTL has expired. > --------------------------------------------------------------------------- > > Key: PHOENIX-5592 > URL: https://issues.apache.org/jira/browse/PHOENIX-5592 > Project: Phoenix > Issue Type: Sub-task > Reporter: Xinyi Yan > Assignee: Xinyi Yan > Priority: Major > Fix For: 4.16.0 > > Time Spent: 0.5h > Remaining Estimate: 0h > > Find the entities from the system catalog which views have TTLs defined on > them.
