Find index uncompressed size

How can I find the index size in my couchbase db. So that I can plan for index growth and storage.

Thanks in advance.

If the index is already created, you can check the “data size”, “disk size” stats in the UI console to see its resource requirements.

Thanks for the response. But I need to calculate the index size for storage and RAM requirements. The indexes are not built yet.

Thanks

Also How can we size for RAM on index nodes ?
