---------------------------------------

             Summary: Continuous query event passed to filter should be immutable for users.
                 Key: IGNITE-2865
                 URL: https://issues.apache.org/jira/browse/IGNITE-2865
             Project: Ignite
          Issue Type: Task
          Components: cache
    Affects Versions: 1.5.0.final
            Reporter: Vladimir Ozerov
            Priority: Critical
             Fix For: 1.6


*Problem*
When event is passed to continuous query filter, it can be used only in scope of this method. The reason is that if filter returns {{false}}, the method {{CacheContinuousQueryEntry.markFiltered()}} is called. This method *clears* key and values.

*Solution*
We should not clear key and values. Instead, we should properly check for {{FILTERED_ENTRY}} flag in all methods where {{key/newVal/oldVal/depInfo}} are used. This includes generated {{readFrom()/writeTo()}} methods as well - their manual change will be required.
