 # Pacemaker
 
-## Intro
+### Intro
 Pacemaker is a storm daemon designed to process heartbeats from workers. As Storm is scaled up, ZooKeeper begins to become a bottleneck due to high volumes of writes from workers doing heartbeats. Lots of writes to disk and traffic across the network is generated as ZooKeeper tries to maintain consistency.
 
 Because heartbeats are of an ephemeral nature, they do not need to be persisted to disk or synced across nodes; an in-memory store will do. This is the role of Pacemaker. Pacemaker functions as a simple in-memory key/value store with ZooKeeper-like, directory-style keys and byte array values.

 The Storm cluster should now be pushing all worker heartbeats through Pacemaker.
 
-## Security
+### Security
 
 Currently digest (password-based) and Kerberos security are supported. Security is currently only around reads, not writes. Writes may be performed by anyone, whereas reads may only be performed by authorized and authenticated users. This is an area for future development, as it leaves the cluster open to DoS attacks, but it prevents any sensitive information from reaching unauthorized eyes, which was the main goal.
