------------------------------
Summary: Support TTL in kudu
Key: KUDU-2868
URL: https://issues.apache.org/jira/browse/KUDU-2868
Project: Kudu
Issue Type: New Feature
Reporter: ZhangYao
In development scenario we usually want to use TTL feature to discard rows that
have not been updated for a while and kudu do not support that yet. Currently
kudu may can use range partition to drop partition out of date to handle TTL
style case but this can not completely cover our needs. Drop partition can not
handle partial updates such as when out of date partition contains rows been
updated recently it can't be dropped. Those long-term non-updated rows are not
needed but still occupying storage space. It's meaningful for kudu to support
row level TTL.
