I have an amazon redshift
cluster with only one node (dc2.large type)
. Now, I want to scale to two nodes and am considering the best way to go (by best I mean as fast as possible).
From the documentation there are about two options:
Is there a way to use a snapshot, but on the same time also change the number of nodes? Or is the unload/copy to/from S3 the only way to do it?
You cannot change the number of nodes when restoring a snapshot.
If you wish to change the number of nodes, then simply tell Redshift to resize the cluster. There is no need to export the data or take a manual snapshot.
