> It's required to add transactional support to
> {code:java}
> org.apache.ignite.internal.table.InternalTable#scan {code}
> binding it to
> {code:java}
> org.apache.ignite.internal.storage.MvPartitionStorage#scan(java.util.function.Predicate<org.apache.ignite.internal.schema.BinaryRow>, java.util.UUID) {code}
> along with acquiring corresponding locks, namely S_commit(table) - if a predicate can produce phantom reads, IS_commit(table) - otherwise.
> Besides transactional support itself, it worth to introduce direct storage reads from within PrimaryReplica instead of going through raft.
