Altering tables within a cluster

I know that it is impossible at the moment. Index should be detached from a cluster before it can be altered.

Is there a chance to implement this feature in the future, so that we can add/drop columns without detaching indexes from a cluster? It would be very useful! We have large indexes which are added to the cluster (after altering) slowly and this causes downtime in our production environment.

Sure thing we will implement easier ALTER in a cluster in the future. However can’t say for sure when exactly we will have time for it.
