Suppose I have read many messages from a source and intend to use a producer to send these messages. The producer typically sends the messages with millisecond differences between one message and the next, and sometimes it sends many messages in the same millisecond.
Regardless, it's important that it sends these messages at specific millisecond intervals.
Is it possible for a Pulsar producer to get backlogged if there are too many messages to send in a short time range of a few milliseconds? - in which case I should have multiple Pulsar producers and round robin between them?
