STL_INSERT

Analyzes insert execution steps for queries.

STL_INSERT is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see Visibility of data in system tables and views.

Note

STL_INSERT only contains queries run on main provisioned clusters. It doesn't contain queries run on concurrency scaling clusters or on serverless namespaces. To access explain plans for queries run on both main clusters, concurrency scaling clusters, and serverless namespaces, we recommend that you use the SYS monitoring view SYS_QUERY_DETAIL . The data in the SYS monitoring view is formatted to be easier to use and understand.

Table columns

Column name	Data type	Description
userid	integer	ID of the user who generated the entry.
query	integer	Query ID. The query column can be used to join other system tables and views.
slice	integer	Number that identifies the slice where the query was running.
segment	integer	Number that identifies the query segment.
step	integer	Query step that ran.
starttime	timestamp	Time in UTC that the query started. Total time includes queuing and execution. with 6 digits of precision for fractional seconds. For example: 2009-06-12 11:29:19.131358.
endtime	timestamp	Time in UTC that the query finished. Total time includes queuing and execution. with 6 digits of precision for fractional seconds. For example: 2009-06-12 11:29:19.131358.
tasknum	integer	Number of the query task process that was assigned to run the step.
rows	bigint	Total number of rows that were processed.
tbl	integer	Table ID.
inserted_mega_value	character(1)	This information is for internal use only. This information shows whether the given insert step has inserted a large value. A large value will be stored in multiple blocks. Block size is 1 MB by default, a large value is greater than 1 MB in a default setting.

Sample queries

The following example returns insert execution steps for the most recent query.

select slice, segment, step, tasknum, rows, tbl
from stl_insert 
where query=pg_last_query_id(); 

 slice | segment | step | tasknum | rows  |  tbl
-------+---------+------+---------+-------+--------
     0 |       2 |    2 |      15 | 24958 | 100548
     1 |       2 |    2 |      15 | 25032 | 100548
(2 rows)
