The archive changes command limits the disk space used by the locally queued CDC events. After the changes from the local queue are applied on the target YugabyteDB database (and source-replica database), they are eligible for deletion.
You can either choose to delete the segments or archive them to a separate location.
Usage: yb-voyager archive changes [ <arguments> ... ]
The following table lists the valid CLI flags and parameters for archive changes command.
When run at the same time, flags take precedence over configuration flag settings.
