Sergi Vladykin commented on IGNITE-1698:
----------------------------------------
I've merged the pull request with the test case into master (with few minor
changes).
The problem is that if we have 0 backups we don't create filter for keys by
primary partition (we assume that we already have only primary entries and thus
there is nothing to filter). But actually we've successfully reserved primary
partitions but few partitions which used to be primary on our node from
previous topology version were not evicted yet and we are getting extra entries
from these ex-primary partitions. We need to add check into
IgniteH2Indexing#backupFilter that eviction of ex-primary partitions is
finished and we will see only primary partitions.
