No delete or update is supported and you cannot define primary keys. +This type of table is suitable for use cases that do not require updates (such as log data synchronization). + +## Distribution + +You also need to define bucket number for Append-only table, see [Bucket]({{< ref "docs/concepts/basic-concepts#bucket" >}}). + +It is recommended that you set the `bucket-key` field. Otherwise, the data will be hashed according to the whole row, +and the performance will be poor. + Review Comment: Bucketing is not only for performance, but also related to the order. I will just change `Distribution` to `Bucketing`. -- This is an automated message from the Apache Git Service.
