yiguolei opened a new issue #1946: Add tablet meta checkpoint mechanism URL: https://github.com/apache/incubator-doris/issues/1946 Currently, there are 3 operations during add a new rowset: 1. add rowset meta to meta store. 2. add rowset to tablet meta in memory. 3. save tablet meta to meta store. 4. remove rowset meta from meta store since it is already in tablet meta. The operation "save tablet meta" is a very heavy operation and it will occupy a lot of bandwidth in ECON [decouple compute and storage] mode. If BE could do tablet meta checkpoint periodly and step 1 and 2 is useful. And there will be only one operation to meta store. It will improve lot of performance in ECON mode.
