An Error Message Is Displayed When a Common User Executes the Statement for Creating or Deleting a GDS or OBS Foreign Table, Indicating that the User Does Not Have the Permission or the Permission Is Insufficient Symptom An administrator can execute the statement for creating a GDS
GS_OBS_LATENCY GS_OBS_LATENCY records the average latency of OBS during the 10 minutes before logtime. The latency is estimated based on OBS operations. This view is supported only by clusters of version 8.2.0 or later.

To query information about OBS/GDS foreign tables such as OBS paths, run the following statement: 1 SELECT * FROM pg_get_tabledef ('foreign_table_name') The following uses table traffic_data.GCJL_OBS as an example: 1 SELECT * FROM pg_get_tabledef('traffic_data.GCJL_OBS'); Parent

GaussDB(DWS) accesses Hudi data on OBS through foreign tables. For details, see section CREATE FOREIGN TABLE (SQL on OBS or Hadoop). Compared with OBS foreign tables, you only need to set format to hudi for Hudi foreign tables.
