Recreating a pipe (using a CREATE OR REPLACE PIPE statement) is necessary to modify most pipe properties.

Recreating Pipes for Automated Data Loads When recreating a pipe that automates data loads using event notifications, it's recommended that Data Engineer complete the following steps:

1. Pause the pipe (using ALTER PIPE … SET PIPE_EXECUTION_PAUSED = true).

2. Query the SYSTEM$PIPE_STATUS function and verify that the pipe execution state is PAUSED.

3. Recreate the pipe (using CREATE OR REPLACE PIPE).

4. Pause the pipe again.

5. Review the configuration steps for your cloud messaging service to ensure the settings are still accurate.

6. Query the SYSTEM$PIPE_STATUS function again and verify that the pipe execution state is RUNNING.
