Hi,

I have a SQL performance issue. There are indexes on both fields that are
used in the ORDER BY clause and the WHERE clause.

The following statement takes about 133941 ms with several warnings from
IgniteH2Indexing:

SELECT JQ._KEY
FROM "JobQueue".JOBQUEUE AS JQ
INNER JOIN "Jobs".JOBS AS J ON JQ.jobid=J._key
WHERE JQ.STATUS = 2
ORDER BY JQ.QUEUED ASC
LIMIT 20

But when I remove the ORDER BY part or the WHERE part from the statement it
returns in <10ms.

What may I do wrong?

Thanks,
Thomas.
