[jira] [Created] (FLINK-27307) Flink table store support append-only ingestion without primary keys.
Zheng Hu created FLINK-27307:
--------------------------------
Summary: Flink table store support append-only ingestion without primary keys.
Key: FLINK-27307
URL: https://issues.apache.org/jira/browse/FLINK-27307
Project: Flink
Issue Type: New Feature
Components: Table Store
Reporter: Zheng Hu
Fix For: table-store-0.2.0
Currently, flink table store only support row data ingestion with defined primary keys. Those tables are quite suitable for maintaining CDC events or flink upsert stream.
But in fact, there are many real scenarios which don't have the required primary keys. Such as user clicks logs, we only need to maintain those data like a Hive/iceberg table. I mean we don't need to define the primary keys, and we don't need to maintain all those rows into a sorted LSM. We only need to partition those rows into the correct partitions and maintain the basic statistics to speed the query.
