[docs] Tablet auto splitting is still marked as BETA

[ddorian]

Tablet autosplitting is GA but is still marked as BETA in https://docs.yugabyte.com/latest/architecture/docdb-sharding/tablet-splitting/#automatic-tablet-splitting-beta and https://docs.yugabyte.com/latest/reference/configuration/yb-master/#tablet-split-size-threshold-bytes

@ddorian Just to make sure I understand: auto tablet splitting is GA and manual is Beta, correct?

@ddorian Have any of the following items been resolved in 2.4 and can be removed from the limitations list? * Presplit tablets remain in the system forever and are not deleted from the disk.

• There is no upper bound on the number of tablets for the table when automatic tablet splitting is enabled.
• During tablet splitting, client applications can get an error from the driver and need to retry the request.
• 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.
• Colocated tables cannot be split.

@mikhpolitov @robertsami @ttyusupov have committed on the feature: #1004 so they can confirm::

auto tablet splitting is GA and manual is Beta, correct?

I'm assuming manual-split is also GA @mbautin

There is no upper bound on the number of tablets for the table when automatic tablet splitting is enabled.

This is done in e028f70

During tablet splitting, client applications can get an error from the driver and need to retry the request.

This is true #5854

If tablet splitting occurs during an ongoing distributed transaction, it could be aborted and need to be retried.

This is true #5854

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.

Fixed in #5523 @robertsami ?

Colocated tables cannot be split.

This should be true, the same as "pull out colocated tables", tracked here: #5239

@ddorian What about "Presplit tablets remain in the system forever and are not deleted from the disk" ?

What about "Presplit tablets remain in the system forever and are not deleted from the disk" ?

I think it's done in #4929 cc @ttyusupov ?

[ttyusupov]

I've updated related docs. Feel free to close this issue if you think #7004 resolved it.

@ddorian @ttyusupov Okay, thanks, I'll leave the following 3 limitations that are listed in the updated architecture doc. Please confirm that I can close the ticket.

• During tablet splitting, client applications may get an error from the driver and need to retry the request.
• If tablet splitting occurs during an ongoing distributed transaction, it could be aborted and need to be retried.
• Since 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.
