is it possible to create Producers WITHOUT creating new threads

[aKumara123]

When a Producer is created (both C++/C APIs), new threads are created.
This discourages (as large no of threads make (Linux)Process monitoring difficult) using large no of Producer objects.

Is there a way to create Producers WITHOUT creating new threads ? (i.e. librdKafka to use already existing threads for it's communication with Kafka Brokers.)
