> Because we only run the combiner after we finished the mapping phase, we need to keep all the results of the mapping phase in memory at once. We should split the output of the mapper into chunks and allow the combiner to process chunks while the mapper is still running, relieving some of the memory pressure. Maybe even block the mapper if there are too many chunks in-flight.

> I can see this error during server restart:
> 10:38:01,682 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 19) JBAS014613: Operation ("add") failed - address: ([
> ("subsystem" => "infinispan"),
> ("cache-container" => "clustered"),
> ("distributed-cache" => "namedCache")
> ]) - failure description: "JBAS010292: org.infinispan.persistence.file.SingleFileStore is not a valid cache store"
> After issuing of operation this configuration fragment is added into standalone.xml configuration file: <store name="genericStore" class="org.infinispan.persistence.file.SingleFileStore" preload="true" passivation="false" purge="false"/>
> Child creation using not generic, but pure File Cache Store option works OK. Store is configured and using this class: org.infinispan.persistence.file.SingleFileStore, however, when trying to do the same using generic store creation, it fails.
> See error in linked JIRA (for loader) as I suspect there is the same cause for this.
