Sample query
Query the progress of converting tablets in the log stream of C replicas on all OBServer nodes of the current tenant to columnar storage.
obclient[SYS]> SELECT * FROM SYS.DBA_OB_CS_REPLICA_STATS;
The query result is as follows:
+----------------+----------+-------+------------------+----------------------+-----------------------+---------------------------+-----------+
| SVR_IP | SVR_PORT | LS_ID | TOTAL_TABLET_CNT | AVAILABLE_TABLET_CNT | TOTAL_MACRO_BLOCK_CNT | AVAILABLE_MACRO_BLOCK_CNT | AVAILABLE |
+----------------+----------+-------+------------------+----------------------+-----------------------+---------------------------+-----------+
| xx.xxx.xxx.212 | 63000 | 1001 | 133 | 133 | 875 | 875 | TRUE |
+----------------+----------+-------+------------------+----------------------+-----------------------+---------------------------+-----------+
1 row in set
Based on the query result, you can estimate the progress of converting rowstore to columnar storage by calculating the value of AVAILABLE_TABLET_CNT / TOTAL_TABLET_CNT or AVAILABLE_MACRO_BLOCK_CNT / TOTAL_MACRO_BLOCK_CNT.
