 Automatic tablet splitting enables resharding of data in a cluster automatically while online, and transparently to users, when a specified size threshold has been reached.
 
-For details on the architecture design, see [Automatic Re-sharding of Data with Tablet Splitting](https://github.com/yugabyte/yugabyte-db/blob/master/architecture/design/docdb-automatic-tablet-splitting.md). While the broader feature is [work-in-progress](https://github.com/yugabyte/yugabyte-db/issues/1004), tablets can be automatically split for a few scenarios starting in the v2.2 release.

 * If tablet splitting occurs during an ongoing distributed transaction, it could be aborted and need to be retried.
-* Because splitting of tablets that are not completely compacted is not yet implemented, tablets created by tablet splitting might be split after they reach the specified size threshold.
