Kafka Connect

Can Kafka Connect be used to read messages from one Kafka Cluster, apply
some basic transformation and write messages to another Kafka Cluster? I
did not find a Kafka Connect Connector in the list of connectors provided
by Confluence[1]. I only found a Replicator[2] but for my use-case I want
to apply some transformation on the messages.

Instead of using Kafka Connect, does it make more sense to use Kafka
Streams or Spark Streaming. I want to perform very simple transformations.
