Ghost meta allows you to store multiple meta values in a single meta record, with an API that mirrors the Metadata API. It integrates with ElasticPress to expand all ghost meta so Elasticsearch can query as normal meta too.
Trying to use the plugin, the plugin will not fail to continue because of the _get_meta_table function ?
What I mean:
update_ghost_meta --> update_metadata --> before trigger the "update_{$meta_type}_metadata" filter there is the _get_meta_table that will fail.
