Ok. One of the issues is that when you have a consumer that consumes
multiple topics, if one of the consumer threads is slow in consuming
messages from one topic, it can block the consumption of other consumer
threads. This is because we use a shared fetcher to fetch all topics. There
is an in-memory queue per topic. If one of the queues is full, the fetcher
will block and can't put the data into other queues.

A workaround is to use different consumer connectors, each consuming a
single topic.

Thanks,
