Check HANA Database Table Size using HANA Studio

SAP HANA database administrator or SQLScript developers can use SAP HANA Studio to check database table sizes on disk to see how much disk space each SAP table uses. Disk space used by each SAP table can be viewed by using HANA Studio Administration cockpit visually or using SQL Console by querying M_TABLE_PERSISTENCE_STATISTICS monitoring table.
