ConsenSys Rollups uses Apache Kafka as the message broker and streaming platform to submit and listen for requests, and get information about batches.
Information about batches is accumulated asynchronously, and notifies the user when a request is submitted and finalized onchain.
Kafka configuration example
[kafka] kafka_type = "Real" brokers = "localhost:9092" timeout_ms = 5000 batch_updates_topic = "sumo-state-updates"
