-----------------------------------
Summary: Use Primary Key Index to Enforce Insert Key Uniqueness
Key: ASTERIXDB-2310
URL: https://issues.apache.org/jira/browse/ASTERIXDB-2310
Project: Apache AsterixDB
Issue Type: Bug
Components: ING - Ingestion, STO - Storage
Reporter: Chen Luo
Assignee: Chen Luo
**Currently when ingesting data using INSERT operations, we always check the
primary index to ensure key uniqueness. However, this implies in most cases all
ingested records might be accessed, which will slow down the ingestion
performance a lot when the records cannot be cached. To handle this, we can
enforce key uniqueness by checking the primary key index, which is much smaller
and can be more easily cached.
