> Key: FLINK-27307
> URL: https://issues.apache.org/jira/browse/FLINK-27307
> Project: Flink
> Issue Type: New Feature
> Components: Table Store
> Reporter: Zheng Hu
> Assignee: Zheng Hu
> Priority: Minor
> Labels: pull-request-available
> 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.
