Prior to Big SQL 4.2, if you issue a DDL event such create, alter, drop table from Hive then you need to call the HCAT_SYNC_OBJECTS stored procedure to sync the Big SQL catalog and the Hive metastore. You use a field dt which represent a date to partition the table. New in Big SQL 4.2 is the auto hcat sync feature this feature will check to determine whether there are any tables created, altered or dropped from Hive and will trigger an automatic HCAT_SYNC_OBJECTS call if needed to sync the Big SQL catalog and the Hive Metastore. This error can occur when you query an Amazon S3 bucket prefix that has a large number its a strange one. Although not comprehensive, it includes advice regarding some common performance, in the AWS Knowledge Center.

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.
