Subject [jira] [Updated] (IGNITE-2893) Atomic structures should not use transactions
Date Mon, 05 Sep 2016 11:20:20 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-2893?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Semen Boikov updated IGNITE-2893:
    Fix Version/s:     (was: 1.8)
       Issue Type: Task  (was: Bug)

This change looks risky: as far as I know, currently in atomic cache EntryProcessor can be
applied twice in case of primary node failure. Need carefully review cache usages for data
structures implementation. Let's move it to 2.0 release.

> Currently atomic structures like {{AtomicReference}}, {{AtomicLong}} and others use transactional
caches and explicit transactions under the hood. This seems redundant, because can be replaced
with atomic cache and {{invoke}} operations with {{EntryProcessor}}.
