Alexander Lapin updated IGNITE-17309:
-------------------------------------
Description:
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.
