Queries on the hosts and services tables that use filters on columns such as labels or custom_values could experience significant performance degradation when many rows were involved. Users might have noticed slow queries or delays when filtering on these columns.

With this fix, the performance of filters on labels and custom_values is now much closer to that of regular columns, resulting in faster and more efficient queries. This improvement enhances your workflow without requiring any manual intervention.
