Reduce size of record offsets

    XMLWordPrintable

    Details

      Description

      Now offsets have stack part and heap part which is used when stack part can not hold that big amount of fields in a table. `mem_heap_t` is used to very wide tables. And the idea is to replace this dichotomy with stack only wider array with optimized offset size: uint16_t instead of ulint.
