(nit) Isn't it probably cleaner and safer (from future changes) to not have _columnsToAddIdx as a private member? Instead just have _indexLoadingConfig as a private member and compute columnsToAddIdx in the respective methods?
This is the pattern followed in other handlers like BloomFilterHandler,H3IndexHandler.

I see BF/H3 hander doesn't hold indexLoadingConfig reference either, but configs for creating BF/H3.
The handlers in this PR don't have specific configs from indexLoadingConfig either, so not hold its reference.

Use a defensive copy to make the IndexHandler methods reentrant and less confusing to use. This is not an issue today, as IndexHandler object is not reused.
