Maksim Zhuravkov updated IGNITE-22204:
--------------------------------------
Description:
IGNITE-16013 incorrectly handles Sort(offset, fetch) transformation. It
transforms:
{noformat}
Sort(ordering=ord, offset=o, fetch=f)
-> Scan
{noformat}
into
{noformat}
Limit (offset=o, fetch=f)
-> Sort(ordering=ord, offset=o, fetch=f)
-> Scan
{noformat}
Which is not correct, because fetch and offset are applied twice.
was:
IGNITE-16013 incorrectly handles Sort(offset, fetch) transformation
It transforms Sort(ordering=abc, offset=o, fetch=f) into Limit (offset=o,
fetch=f) -> Sort(ordering=abc, offset=o, fetch=f), which is not correct, since
fetch and offset are applied twice.
