Vladislav Pyatkov updated IGNITE-20292:
---------------------------------------
Description:
We have several tests that check a scan-read for the sorted index. The tests
are mostly green in TC, but if you cycle them, they frequently fail.
Perhaps this issue is connected with the latest change in transaction protocol,
one-pase-commit. This was investigated by git-bisect, but it could also be just
a coincidence.
Look at the test ItTableScanTest#testPhantomReads, it fails almost 10% of the
time it runs on my local machine.
