| Description |
|
As reported at: https://github.com/mariadb-corporation/mariadb-columnstore-server/issues/3 MariaDB has a hard limit of 4096 columns which prohibits the number of columns ColumnStore can use. It will likely be a lot of work to modify MariaDB's internals to support a higher column count so setting this as 'Minor' for now. |

It boils down to 2-byte offset in FRM format. This should't be a very big problem. |
