---------------------------------
Summary: master should delete table info if table deleted, instead
of keeping them forever
Key: KUDU-3097
URL: https://issues.apache.org/jira/browse/KUDU-3097
Project: Kudu
Issue Type: New Feature
Reporter: wangningito
Recently I addressed a memory problem occurred by kudu master.
Related info:
Master memory report by system , 8.6g
Master memory report by kudu web page, 1g
The master keep running from 2018 to now, and still running.
During two years, I create over 30000 tables and delete them for test
requirement. And we keep only 20 tables running during those time.
I found the memory usage strange, so I tried to dump all the data of master via
"kudu lcoal_replica dump rowset 000000000 ..."
I found over 330k records in the environment. And the records are just mark as
deleted.
Guess this could cause be the burden for master, and some untracked memory.
