If txn1 begin after SNAPBUILD_BUILDING_SNAPSHOT and commit before
SNAPBUILD_FULL_SNAPSHOT(so txn1 will not be processed by DecodeCommit), and
txn2 begin after SNAPBUILD_FULL_SNAPSHOT and commit after
SNAPBUILD_CONSISTENT(so txn2 will be replayed), how to ensure that txn2
could see the changes made by txn1?

Thanks
