defaultRequestTimeoutMs

public abstract int defaultRequestTimeoutMs

Represents the kafka configuration property request.timeout.ms - for both consumer and producers.

Kafka's default value is 30000.

This should be larger than replica.lag.time.max.ms (a broker configuration) to reduce the possibility of message duplication due to unnecessary producer retries. The default for replica.lag.time.max.ms is 20000.
