[jira] [Updated] (IGNITE-16096) Implement MVCC support to avoid excessive locking

     [ https://issues.apache.org/jira/browse/IGNITE-16096?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexey Scherbakov updated IGNITE-16096:
---------------------------------------
    Description: 
We need to implement MVCC support to avoid locking and resulting conflicts.

Generally, the idea is to use monotonic timestamps to globally order the transactions.

See [1][2] for decentralized timestamp generation techniques,  [3]for MVCC analysis:
