+      Brokers:
+        - "172.16.186.16:19092"
+        - "172.16.186.17:19092"
+      Topic: k8slog

+go-stash is a high performance, free and open source server-side data processing pipeline that ingests data from Kafka, processes it, and then sends it to ElasticSearch. 
+
+go-stash is about 4x throughput more than logstash, and easy to deploy, only one executable file.
