Internally the cache will be expired after it's idle for 2 hours. User can verify whether a query can leverage BloomFilter datamap by executing `EXPLAIN` command, which will show the transformed logical plan, and thus user can check whether the BloomFilter datamap can skip blocklets during the scan.
