BE

- in the log, We often print tablet id, schema hash
- The schema hash is recorded in TabletMetaManager, and some are recorded in the keys of rocksdb
- The schema hash is recorded in RowsetMeta, it is not used.
- TabletManager such as getTablet, drop Tablet.
- Various Task executions on BE, such as alter task, clone task
- Many http actions provided by BE require schema hash as a parameter
- Meta Tools
FE
- Available in Catalog, Tabletmeta
- The schema hash in the report handler is removed to prevent the tablet from being deleted by mistake
