Subject [jira] [Resolved] (IGNITE-5795) @AffinityKeyMapped ignored if QueryEntity used
Date Fri, 04 Aug 2017 15:04:00 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-5795?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alexey Kukushkin resolved IGNITE-5795.
--------------------------------------
    Resolution: Workaround

I discussed this with [~vozerov] and confirmed we do not want to fix this since any fix would
violate Ignite design ideology. 
To work around the problem in addition to specifying affinity key field using @AffinityKeyMapped
annotation also specify it in the cache key configuration like this:
<property name="cacheConfiguration">
<list>
<bean class="org.apache.ignite.configuration.CacheConfiguration">
...
<property name="keyConfiguration">
<bean class="org.apache.ignite.cache.CacheKeyConfiguration">
<property name="typeName" value="TYPE_NAME"/>
<property name="affinityKeyFieldName" value="AFFINITY_KEY_FIELD_NAME"/>
</bean>
</property>
</bean>
</list>
</property>
Resolving this issue with a fix.

> When cache configured with QueryEntity and used key type with @AffinityKeyMapped field,
it will be ignored and wrong partition calculated. This happens because QueryEntity processing
precedes key type registering in binary meta cache. On that step CacheObjectBinaryProcessorImpl#affinityKeyField
called and unable to resolve type, so null returned and null putted in affKeyFields.
> On next put/get operation CacheObjectBinaryProcessorImpl#affinityKeyField will return
null from affKeyFields, but should be affinity key field.
> Test that reproduces problem in [PR 2330|https://github.com/apache/ignite/pull/2330]
> To wrorkaround the issue, set IgniteConfiguration#setKeyConfiguration(), it will force
registering key.
