Macro Definition Documentation
| #define REC_VERSION_56_MAX_INDEX_COL_LEN 3072 |
Maximum indexed field length for table format UNIV_FORMAT_B and
beyond. This (3072) is the maximum index row length allowed, so we cannot create index prefix column longer than that.
Enumeration Type Documentation
| enum rec_format_enum |
Innodb row types are a subset of the MySQL global enum row_type.
They are made into their own enum so that switch statements can account for each of them.
