Subject [jira] [Assigned] (IGNITE-809) Old value can be missed for tx near cache entry
Date Fri, 25 Sep 2015 09:01:04 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-809?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Semen Boikov reassigned IGNITE-809:

    Assignee: Alexey Goncharuk  (was: Semen Boikov)

Looks like this is failure scenario (all operations for the same key):
- put some value in cache from primary node
- start two invoke transactions: tx1 from primary node, tx2 from near node
- primary receives GridNearTxPrepareRequest for tx2, adds near node as reader, but tx2 is
not finished yet
- primary maps tx1, sees that there is reader, GridNearTxRemote is created/committed on near
node, but old value is not passed on near node

Alexey, please take a look.
