---------------------------------
Resolution: Fixed
> Primary Key Index is not properly maintained by upsert feeds
> ------------------------------------------------------------
>
> Key: ASTERIXDB-2429
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2429
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: ING - Ingestion, STO - Storage
> Reporter: Chen Luo
> Assignee: Chen Luo
> Priority: Major
>
> During upsert, the primary key index is not properly maintained and is always
> empty. The problem is that when upserting secondary indexes, we generate new
> values and old values to clean up secondaries. However, since there is no
> secondary key for the primary key index, the old value would always points to
> the new primary key. As a result, LSMSecondaryUpsertOperator would always
> think the secondary key values do not change, ignoring maintaining the
> primary key index.
