| - The PK-index worker keeps a keyed row-position index of the target branch in Flink state. Its size scales with the number of live rows in the table for the configured equality columns; size Flink state backend, checkpoint storage, and TaskManager memory accordingly. |

[for my understanding] is this done in an incremental manner from the last check-pointed state ?

| **Concurrent commits on the target branch** | ||
|
|

| - External commits to the target branch (e.g. compaction, direct writes) are detected by `RowDelta.validateFromSnapshot`. A conflicting cycle fails at commit; the next trigger reindexes the worker's PK index from the new target head and retries. |

Do we wanna put a recommendation to avoid concurrent writes to the tables ? i understand we can rebase / re-index and then retry but i wonder how practical it is for the next attempt to succeed if there is another writer writing to the table continuously
