Description
In order to fix MCOL-4871, ColumnStore needs two new functions in MY_COLLATION_HANDLER:
/* |
Make minimum and maximum strings for the collation.
|
Put not more than "nchars" characters.
|
*/
|
size_t (*min_str)(CHARSET_INFO *cs, uchar *dst, size_t dstlen, size_t nchars); |
size_t (*max_str)(CHARSET_INFO *cs, uchar *dst, size_t dstlen, size_t nchars); |
Note, this functionality is not needed in the server at this point. No MTR tests are possible. So tests should be done in unittest/strings/strings-t.c.
