Refreshing external tables automatically¶
Event notifications for cloud storage can trigger refreshes of the external table metadata or add or drop file references.
Important
Transferring ownership on an external table or its parent database with the GRANT OWNERSHIP command
sets the table’s AUTO_REFRESH
property to FALSE
. This blocks automatic refreshes of the table metadata.
To restore automatic refreshes after you transfer ownership, set AUTO_REFRESH = TRUE
using the ALTER EXTERNAL TABLE command.
