[GitHub] [incubator-doris] kangpinghuang opened a new issue #2665:
[Optimization] add close api to rowset
kangpinghuang opened a new issue #2665: [Optimization] add close api to rowset
URL: https://github.com/apache/incubator-doris/issues/2665
**Is your feature request related to a problem? Please describe.**
Now singleton rowsets will be reserved for 30min after it is added to unused rowset for increment clone. But it will never be used to create rowset reader and hold the file handler and index resources in memory, which is costly, especially in frequent load situation, which will incur Too Many Open file error.
So it is necessary to add a close api to release the resource owned by rowset when it it added to unused rowsets queue.
BTW, some things should be considered are:
1. the unused rowset may be owned by some readers, we should not release the resources before these delayed readers finish reading.
