Understanding Event Publishers
There are 3 ways of publishing events : AMPQ 1.0, Kafka Protocol or HTTPS.
We can publish events individually or batched : A single publication has a limit of 1 MB regardless of whether it’s a single event or a batch. Publishing events larger than 1 MB will be rejected.
