+Apache Kafka is publish-subscribe messaging rethought as a 
+distributed commit log.
+
+Fast
+    A single Kafka broker can handle hundreds of megabytes 
+    of reads and writes per second from thousands of clients.
+
+Scalable
+    Kafka is designed to allow a single cluster to serve as 
+    the central data backbone for a large organization. It 
+    can be elastically and transparently expanded without 
+    downtime. Data streams are partitioned and spread over a 
+    cluster of machines to allow data streams larger than the 
+    capability of any single machine and to allow clusters of 
+    co-ordinated consumers
+
+Durable
+    Messages are persisted on disk and replicated within the 
+    cluster to prevent data loss. Each broker can handle 
+    terabytes of messages without performance impact.
+
+Distributed by Design
+    Kafka has a modern cluster-centric design that offers 
+    strong durability and fault-tolerance guarantees.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
