In Big SQL 4.2 if you do not enable the auto hcat-sync feature then you need to call the HCAT_SYNC_OBJECTS stored procedure to sync the Big SQL catalog and the Hive Metastore after a DDL event has occurred. This can be done by executing the MSCK REPAIR TABLE command from Hive. Data protection solutions such as encrypting files or storage layer are currently used to encrypt Parquet files, however, they could lead to performance degradation.
