2.2.5 Checking Load Status

You can check if tables are loaded by querying the LOAD_STATUS data from HeatWave Performance Schema tables. For example:

mysql> USE performance_schema;
mysql> SELECT NAME, LOAD_STATUS
          FROM rpd_tables,rpd_table_id
          WHERE rpd_tables.ID = rpd_table_id.ID;
+------------------------------+---------------------+
| NAME                         | LOAD_STATUS         |
+------------------------------+---------------------+
| tpch.supplier                | AVAIL_RPDGSTABSTATE |
| tpch.partsupp                | AVAIL_RPDGSTABSTATE |
| tpch.orders                  | AVAIL_RPDGSTABSTATE |
| tpch.lineitem                | AVAIL_RPDGSTABSTATE |
| tpch.customer                | AVAIL_RPDGSTABSTATE |
| tpch.nation                  | AVAIL_RPDGSTABSTATE |
| tpch.region                  | AVAIL_RPDGSTABSTATE |
| tpch.part                    | AVAIL_RPDGSTABSTATE |
+------------------------------+---------------------+

The AVAIL_RPDGSTABSTATE status indicates that the table is loaded. For information about load statuses, see Section 7.3.9, “The rpd_tables Table”.
