using DataStreamer. " +
+ "The processor uses the value of FlowFile attribute (Ignite cache
entry key) as the " +
+ "cache key and the byte array of the FlowFile as the value of the
cache entry value. Both the string key and a " +
+ " non-empty byte array value are required otherwise the FlowFile is
transfered to the failure relation. " +
+ "Note - The Ignite Kernel periodically outputs node perforance
statistics to the logs. This message " +
+ " can be turned off by setting the log level for logger
'org.apache.ignite' to WARN.")
