Parsec

Contains the Parsec specifications, and an implementation of the protocol using Kafka

Run

To run the ParsecSimulator that will generate Parsec Protocol messages on Kafka topics: Just edit the KProducer.scala run:

sbt simulator/run

Kafka cluster

You can see the schemas as they are registered in the schema-registry-ui

You can view the messages as they are shown in the kafka-topics-ui

A bit of theory

Decide on State management implementation. KStreams is a good choice:

• partition aware (it auto handles partitioning when scaling)
• state keeping is like samza but improved from functionality from Google
• persists on RocksDB and compacted topics
• it persists on RocksDB and compacted topics
• it resumes from where it left when it crashes
