Description
This references these two global variables which no longer exist in percona-server 8.0:
innodb_mem_adaptive_hash innodb_mem_dictionary
I can't pinpoint exactly when they were dropped from storage/innobase/srv/srv0srv.cc, but they're definitely gone in every 8.0 release. The related output variables in SHOW ENGINE INNODB STATUS;, section "BUFFER POOL AND MEMORY" are missing as well:
| 5.7 output | 8.0 output |
