### Kinesis Consumer

I think we should also mention the threading model of the Kinesis consumer
in the documentation.
Users should know that each parallel Flink instance will constantly query
Kinesis for shards. So if a user has 5 shards, but runs Flink with a
parallelism of 50, there will be 50 threads constantly querying Kinesis.
Also, we should explain that there will always be one thread per shard
running.
