<!-- TODO: reintroduce flume -->
-Connectors provide an interface for accessing data from various third
party sources (message queues). Currently three connectors are natively
supported, namely [Apache Kafka](https://kafka.apache.org/),
[RabbitMQ](http://www.rabbitmq.com/) and the [Twitter Streaming
API](https://dev.twitter.com/docs/streaming-apis).
+Connectors provide code for interfacing with various third-party systems.
+Currently these systems are supported:
-Typically the connector packages consist of a source and sink class (with
the exception of Twitter where only a source is provided). To use these sources
the user needs to pass Serialization/Deserialization schemas for the connectors
for the desired types. (Or use some predefined ones)

Should we add source/sink, to show which types of connectors are

We can also add Java/Scala collections and file systems (HDFS) to that list.
