aws elasticache create-replication-group doesn't support repartition #2503

Closed tchia04 closed 7 years ago

tchia04 commented 7 years ago

The enhanced redis backup and restore with cluster resizing has been announced at https://aws.amazon.com/about-aws/whats-new/2017/03/amazon-elasticache-launches-enhanced-redis-backup-and-restore-with-cluster-resizing/

However using the latest version of awscli which as of today is 1.11.63 still doesn't support using different number of RDB file than the number of shards.

I still see this in the help file. 

   --snapshot-arns (list)
      A  list  of  Amazon  Resource Names (ARN) that uniquely identify the
      Redis RDB snapshot files stored in Amazon S3. The snapshot files are
      used to populate the replication group. The Amazon S3 object name in
      the ARN cannot contain any commas. The list must match the number of
      node  groups (shards) in the replication group, which means you can-
      not repartition.

      NOTE:
          This parameter is only valid if the Engine parameter is redis  .

      Example of an Amazon S3 ARN: arn:aws:s3:::my_bucket/snapshot1.rdb

Also how do I do "Equal distribution" that I can do from the console UI?

This kind of question specific to the usage of a service is better asked on the service forums or on stackoverflow. There are too many new services and features coming out for us on the CLI team to be experts in their usage.
