This feature helps users periodically delete obsolete data. For partition boundaries If the period unit is hour, the start boundary value is the coming hour, and the partition interval is the value of period.
For example, ddl_sequence indicates that the audit type is sequence-related operations. dml_action_insert/dml_action_delete/dml_action_update/dml_action_merge/dml_action_select Indicates that the audit type is DML operations such as INSERT, DELETE, UPDATE, and MERGE. internal_event
If this parameter is set to true or on, the GDS process will automatically delete a named pipe file. If this parameter is set to false or off, the GDS process will not delete a named pipe file. When setting del_pipe, set file_type to pipe or interconn.

allows users to delete data from specified tables.
In this case, run DROP FOREIGN TABLE order01 to delete the foreign table, create a foreign table again, and run the following statement to import data again. 1 INSERT INTO orders SELECT * FROM orders01; Repeat the preceding steps to log in to the destination cluster dws-demo02 and
example): Remove the association between the current sequence and the target table. 1 2 ALTER SEQUENCE mytable_b_seq owned by none; ALTER TABLE mytable alter b drop default; Record the current sequence value as the start value of the new sequence. 1 SELECT nextval('mytable_b_seq'); Delete
In scenarios where UPSERT, UPDATE, and DELETE operations are concurrently performed on column-store tables, these operations cannot be concurrently performed because they need to wait for the CU lock. This problem cannot be solved even if the DELTA table is enabled.
A common user cannot create, modify, delete, or assign tablespaces, and needs to be assigned the permission for accessing tablespaces.

CheckDDL Start a transaction to delete schemas and tables. If the transaction can be committed, the inspection passes. Otherwise, the inspection fails. CheckTimeZone The inspection passes if all nodes in the cluster use the same time zone, and fails if they do not.
Return type: SETOF record pg_stat_get_last_data_changed_time(oid) Description: Returns the time when INSERT, UPDATE, DELETE, or EXCHANGE/DROP PARTITION was performed last time on a table.
Format: no_merge (current query) and no_merge(relid) (specified object). 3 DML hints Added support for hints in INSERT, UPDATE, MERGE, and DELETE statements. 4 AGG redistribution hints support specified column names. Column names can be specified for AGG redistribution hints.
However, the primary key column must be set during deletion, and the "column update does not take effect" is ignored. public void delete() throws DwsClientException { getClient().delete("test.test") .setObject("id", 1) // Asynchronously save the data to the
