Locate the row that contains the target elastic pool and click Edit in the Operation column to delete nodes from the elastic pool (move the selected ring from the left to the right). A host ring with CN nodes cannot be scaled in.
The last change time of a table is recorded only on the CN where INSERT, UPDATE, and DELETE operations are performed. Therefore, you need to query tables that are changed within the last day (the period can be changed in the function).
CALL dynamic_proc(); -- Delete the stored procedure. DROP PROCEDURE dynamic_proc; OPEN FOR Dynamic query statements can be executed by using OPEN FOR to open dynamic cursors. For details about the syntax, see Figure 3.
Add, Delete, Modify, and Query operations on entire rows are frequently performed. Column storage Only necessary columns in a query are read. The homogeneity of data within a column facilitates efficient compression.
Frequently update and delete operations can lead to table bloating. To free up space, you can run the VACUUM or VACUUM FULL command on system catalogs.
Value range: enumerated values origin indicates that the system copies operations such as insert, delete, and update from the current session. replica indicates that the system copies operations such as insert, delete, and update from other places to the current session. local indicates
Create a replication table node group using the CREATE NODE GROUP SQL statement and delete one using DROP NODE GROUP. Before deleting a replication table node group, delete all table objects in the node group.
Each subquery can be a SELECT, VALUES, INSERT, UPDATE or DELETE statement.
After executing batch INSERT and DELETE operations, you are advised to run the ANALYZE statement on the table or the entire database to update statistics. By default, 30,000 rows of statistics are sampled.
When you cannot log in to Data Studio due to a damaged security key, perform the following steps to generate a new security key: Delete the security folder in Data Studio > UserData.
If the retention period of an incremental snapshot exceeds the maximum retention period, GaussDB(DWS) does not delete the snapshot immediately.
After the separation of duties is enabled, only the system administrator has the permission to create, modify, delete, and allocate logical clusters. Accessing a logical cluster requires permissions.
You can check it in the snapshot list and manually delete it if it is no longer necessary. During the change, the cluster is read-only, affecting intelligent O&M tasks. You are advised to start these tasks after the change or pause them before the change.

After confirming that the information is correct, enter DELETE or click Auto Enter and click OK to delete the cluster. The cluster status in the cluster list will change to Deleting and the cluster deletion progress will be displayed.

Deleting a Parameter Template You can delete an unnecessary parameter template or a parameter template that is no longer used. The default parameter template cannot be deleted. Deleted parameter templates cannot be restored. Exercise caution when performing this operation.
Data Studio allows you to reset counters in the following pages: Display DDL Tablespace, Display DDL User/Role, Batch Delete, Result Set, and Execution Plan. Data Studio displays an error message indicating that no result is found in the status bar.
