The `@Filter` annotation is another way to filter out entities or collections using custom SQL criteria, for both entities and collections.

The `@Filter` annotation is another way to filter out entities or collections using custom SQL criteria.

Unlike the `@Where` annotation, `@Filter` allows you to parameterize the filter clause at runtime.

This limitation is due to ensuring consistency and because the filtering information is not stored in the second-level cache.

If caching was allowed for a currently filtered collection, then the second-level cache would store only a subset of the whole collection.

When using the `@Filter` annotation with collections, the filtering is done against the child entries (entities or embeddables).

However, if you have a link table between the parent entity and the child table, then you need to use the `@FilterJoinTable` to filter child entries according to some column contained in the join table.
