Subject [jira] [Updated] (IGNITE-3484) MVCC for cache data structures
Date Thu, 14 Jul 2016 21:46:20 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-3484?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dmitriy Setrakyan updated IGNITE-3484:
--------------------------------------
    Description: 
We need to make sure that SQL queries are executed on a certain in-memory timestamp or version.
This will require having as many versions of data in memory as needed by the ongoing SQL queries.
Once the queries complete, the older versions should be discarded.

TBD: design requirements for MVCC.
