Error Message "org.postgresql.util.PSQLException: ERROR: tuple concurrently updated" Is Displayed When the System Executes insert overwrite on a Datasource GaussDB(DWS) Table
Symptom
The system failed to execute insert overwrite on the datasource GaussDB(DWS) table, and org.postgresql.util.PSQLException: ERROR: tuple concurrently updated was displayed.
Cause Analysis
Concurrent operations existed in the job. Two insert overwrite operations were executed on the table at the same time.
One CN was running the following statement:
TRUNCATE TABLE BI_MONITOR.SAA_OUTBOUND_ORDER_CUST_SUM
Another CN was running the following command:
call bi_monitor.pkg_saa_out_bound_monitor_p_saa_outbound_order_cust_sum
This function deletes and inserts SAA_OUTBOUND_ORDER_CUST_SUM.
Procedure
Modify job logic to prevent concurrent insert overwrite operations on the same table.
