"Elimination fo char/varchar" should be "Elimination for char/varchar" ?

Comment by Andrew Hutchings (Inactive) [ 2019-10-24 ]

Use X-byte prefixes of the string into partition ranges to allow extent elimination for string store.

Potentially use footprint of string.

The "create date" on this ticket is pre-convergence with MariaDB server. If the issue still exists in a modern version of the engine/plugin please submit a new ticket.
