Removing query_cache ops that are no longer supported in MySQL >= 8.0 #1107

@ernstae ernstae commented Aug 3, 2018

While using MySQL 8.0, the configuration options in the mysqld params section had query_cache_limit and query_cache_size variables which are no longer supported for MySQL >= 8.0

Moving these into the version-specific hashes, rather than the mysqld default hash. I didn't love having to duplicate those entries, but it does follow the same pattern of the myisam-recover option. 🤷‍♂️

This results in MySQL 8.0.12 actually starting up, rather than throwing the following error example:

[ERROR] [MY-011071] [Server] unknown variable 'query_cache_limit=1M'

Users who are looking to override this variable can always undef it in hiera:

    query_cache_limit: ~
    query_cache_size: ~

To override query_cache_size and query_cache_limit, you have to set the specific version:

    query_cache_size: ~

The options in mysqld will be overrided from the default values:
