InnoDB only reserves 13 bits for the heap number in the record header, limiting the heap number to be at most 8191. But, when using innodb_page_size=64k and secondary index records of 7 bytes each, it is possible to exceed the maximum heap number. btr_cur_optimistic_insert(): Let the operation fail if the maximum number of records would be exceeded. page_mem_alloc_heap(): Move to the same compilation unit with the only caller, and let the operation fail if the maximum heap number has been allocated already. |
