Re: Unable to create collection in 5.5

[Yago Riveiro]

Because I have codebase that relay in logic to resolve the name of
collections.

  

With this modification I'm forced to have logic to handled old and new
collections when this should be transparent.

  

If I have collection collection-1, collection-2, collection-3 created with a
external tool, upgrading to 5.5 now I have collection-1, collection-2,
collection-3 and collection_x.

  

A way to resolve this problem can be aliases, but the collection API doesn't
list the aliases in LIST command and read the noise CLUSTERSTATE command to
fetch collections (and aliases) in cluster with thousand of collections is
like no-no.  
  

Sorry but without a way to rename old collection to collection_*, the enforce
to do not allow hyphens is frustrating as a user.

continue to work just fine. Do you mean that the restriction doesn't allow  
you to e.g. add a shard with a valid name, to an older collection ?
