 Here is some information on actually running Kafka as a production system based on usage
and experience at LinkedIn. Please send us any additional tips you know of.
 
 <h1><a id="datacenters">Datacenters</a></h1>
+
 Some deployments will need to manage a data pipeline that spans multiple datacenters. Our
approach to this is to deploy a local Kafka cluster in each datacenter and machines in each
location interact only with their local cluster.
 <p>
 For applications that need a global view of all data we use the <a href="/08/tools.html">mirror
maker tool</a> to provide clusters which have aggregate data mirrored from all datacenters.
These aggregator clusters are used for reads by applications that require this.

 <p>
-Likewise in order to support data load into Hadoop which resides in separate facilities we
provide local read-only clusters that mirror the production data centers in the facilities
where this data load occurs.
+Likewise, in order to support data load into Hadoop, which resides in separate facilities,
we provide local read-only clusters that mirror the production data centers in the offline
facilities.
 <p>
 This allows each facility to stand alone and operate even if the inter-datacenter links are
unavailable: when this occurs the mirroring falls behind until the link is restored at which
time it catches up.

 <p>
 It is generally not advisable to run a single Kafka cluster that spans multiple datacenters
as this will incur very high replication latency both for Kafka writes and Zookeeper writes
and neither Kafka nor Zookeeper will remain available if the network partitions.

 <h1><a id="config">Kafka Configuration</a></h1>
 Kafka 0.8 is the version we currently run. We are currently running with replication but
with producers acks = 1.
