Think of json index as an inverted index. It is extremely expensive to use inverted index as forward index because each value read requires scanning the whole inverted index. For group-by clause itself, we can potentially use inverted index to accelerate the query processing, but that is also not easy and we don't have that support for regular inverted index yet. -- This is an automated message from the Apache Git Service.
