Apache Pulsar
Pinot supports consuming data from Apache Pulsar via pinot-pulsar plugin. You need to enable this plugin so that Pulsar specific libraries are present in the classpath. 
You can enable pulsar plugin with the following config at the time of Pinot setup
-Dplugins.include=pinot-pulsar 
pinot-pulsar plugin is not part of official 0.10.0 binary. You can download the plugin from our external repository and add it to libs or plugins directory in pinot.
