Today Pinot supports group-by json-extract-scalar already but in the worst possible by parsing every possible json string. It caused massively oom and timeout even with 1 query. Using the json index would be a huge improvement over that. Pinot json index today already collects and sort json path+value. Group by json path (e.g. $a.b) can take average of the sorted dictionary to quickly locate the portion of the dictionary ids. I think doing this will provide great speed up compared with what we have today. We are working on a proof of concept and will share the test results soon. -- This is an automated message from the Apache Git Service.
