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

This statement is understood to be fully compatible with MySQL. Any compatibility differences should be reported via an issue on GitHub.
