------------------------------------------
Summary: Implement a pending update storage
Key: IGNITE-18502
URL: https://issues.apache.org/jira/browse/IGNITE-18502
Project: Ignite
Issue Type: Improvement
Reporter: Vladislav Pyatkov
*Motivation*
All tables have a transactional nature, even if we don't use transactions
explicitly. That means all entry are storied as write intents (pending entries)
before they will be committed. Those entries are required for transactional
protocol and storied in memory collection
(_PartitionListener#txsPendingRowIds_). The collection can be lost due to
restart the node where the data located. Recovery of the collection happens
through scan all entries in the partition and can require huge time.
*Definition of Done*
After storage will be implemented, the pending entries' collection should be
replaced to it.
The storage should recover itself in order to do not scan partition on start.
