Aggregate/Order should be avoiding produce result on error

INSERT INTO default (KEY TO_STR(k), VALUE v)

SELECT  {"a":d, k, "comment":RPAD("a",1000,"b")} AS v

FROM ARRAY_RANGE(0,10000) AS d

UNNEST ARRAY_RANGE(0,5000) AS u

LET k = (d*5000)+u;

Create Primary index on default;

SELECT d.a, COUNT(1) AS cnt

FROM default AS d

GROUP BY d.a

ORDER BY cnt DESC

LIMIT 20;

Generate error By setting the backfill size to small .

As this stop and go due to aggregate/order by. When error it should stop. Should not continue or give wrong info.

At least error from indexer client should treat as Fatal and don't accumulate till allowed Limit.
