Get the byte array from Ignite Cache and adds it as the content of a FlowFile.The processor uses the value of FlowFile attribute (Ignite cache entry key) as the cache key lookup. If the entry corresponding to the key is not found in the cache an error message is associated with the FlowFile Note - The Ignite Kernel periodically outputs node performance statistics to the logs. This message can be turned off by setting the log level for logger 'org.apache.ignite' to WARN in the logback.xml configuration file.
