REFRESH TABLEcommand for each table. This command invalidates the cached entries for Apache Spark cache, which include data and metadata of the given table or view. The invalidated cache is populated lazily when the cached table or the associated query is executed again. Here’s an example syntax:REFRESH TABLE table_name1; REFRESH TABLE table_name2; REFRESH TABLE table_name3;Where
table_name1,table_name2, andtable_name3identify the Delta tables or views to cache. Please note thatREFRESH TABLEis not applicable for refreshing the data in streaming tables and materialized views. You can use theREFRESH (MATERIALIZED VIEW and STREAMING TABLE)command. -
