Excuse me. One data table can be split into multiple tablets . Why can tablets be split into Parent tablets and Child tablets? What is the relationship between parent tablets and child tablets? Is there a specific data instance to show? Thanks a lot.

So it’s here https://github.com/yugabyte/yugabyte-db/blob/e3ad1493801b137d78e5431b67ad818da3c1f80a/src/yb/master/tablet_split_manager.cc#L541 . The context here is on “automatic tablet splitting” https://docs.yugabyte.com/preview/architecture/docdb-sharding/tablet-splitting/#automatic-tablet-splitti…

Hi, There’s nothing like parent and child tablets. The SQL tables are sharded on their primary key (and indexes on their key) to distribute the rows to tablets. Those are distributed and replicated on the cluster.

Hi.
I am reading the source file tablet_split_manager.c.
I saw some descriptions of parent and child tabs in the relevant functions.
