> CatalogServiceCatalog.isBlacklistedDb() is used in many places to check if a given database name is on the list of databases which should be ignored in Catalog. However it does a case sensitive comparison which could cause false negatives.
> One place where we see this issue is when we receive a metastore event on the on {{SYS}} database and the {{--blacklisted_dbs}} is set to \{{sys}}. In such cases EventsProcessor should ignore the event instead of processing it.
