Description

Schema hash is not used any more, we should remove it and keep our code more clear. Schema hash is used in may places:

BE

• used in various paths, such as snapshot path, trash path, tablet's path
• 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
• The query task sent by Fe to BE, as well as in various tasks
