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.
