chaoyli opened a new pull request #2620: Set AGG_KEYS upon upgrade from tablet if has_keys_type() is false URL: https://github.com/apache/incubator-doris/pull/2620 Doris support AGG_KEYS/UNIQUE_KEYS/DUP_KEYS/ three storage model. Among these three model, UNIQUE_KYES/DUP_KEYS is added after AGG_KEYS. For historical tablet, the keys_type field to indicate storage model may be missed for AGG_KEYS.
