Pre-split region

If the table to be copied is defined with the PRE_SPLIT_REGIONS attribute, the table created using the CREATE TABLE LIKE statement inherits this attribute, and the Region on the new table will be split. For details of PRE_SPLIT_REGIONS, see CREATE TABLE Statement.

MySQL compatibility

The CREATE TABLE LIKE statement in TiDB is fully compatible with MySQL. If you find any compatibility differences, report a bug.
