GS_SPM_ID_HASH_JOIN

GS_SPM_ID_HASH_JOIN is a system catalog in the SPM feature. Currently, this feature is not supported in the distributed system. The system catalog stores the relationship between unique_sql_id and sql_hash. Users with sysadmin permissions can read the system catalog, but only the initial user can write data to the system catalog.

**Table 1** GS_SPM_ID_HASH_JOIN columns
Name	Type	Description
unique_sql_id	bigint	Unique ID of an SQL statement in the database.
sql_hash	bigint	Unique ID of the SQL statement in the SPM.
