We are trying to create a new index in production depending on whether a feature is enabled or not. As soon as the feature gets turned on, we setup 3 different indexes. This also means 3 different indexes have to be built. Will the index build lock buckets from being read and written from?
Bucket operations will not be blocked.
If you need create 3 indexes, create all 3 indexes in defer mode and use build index command to build all 3 indexes one time (check defer_build in following document for advantages).
