Maxim Muzafarov updated IGNITE-5836: ------------------------------------ Fix Version/s: (was: 2.8) > AffinityFunctionContext should provide consistent previous assignment > --------------------------------------------------------------------- > > Key: IGNITE-5836 > URL: https://issues.apache.org/jira/browse/IGNITE-5836 > Project: Ignite > Issue Type: Bug > Components: cache > Affects Versions: 2.0 > Reporter: Valentin Kulichenko > Priority: Critical > Labels: usability > > Currently each cache maintains its own {{AffinityFunctionContext}}. This > leads to the case that {{previousAssignment}} can be different for two caches > created on different topology versions. In particular, this broke > {{FairAffinityFunction}} which was removed because of that. > We should do the following: > * Make sure that {{previousAssignment}} is consistent for all caches with > same affinity function, regardless of topology versions caches were created > on. > * Add mechanism to enforce equality check for affinity functions. We probably > will need to force user to implement {{equals}} for cache node filter and > backup filter. > * When above is done, bring back {{FairAffinityFunction}}. > This is also discussed on dev list: > http://apache-ignite-developers.2346864.n4.nabble.com/Resurrect-FairAffinityFunction-td19987.html -- This message was sent by Atlassian Jira (v8.3.4#803005)
