About this pageAI generated

This page describes building a Java microservice called Broker Asset API using Spring Boot, Redis, and Flyway to process market data. A Python service publishes B3 data to Kafka, which the Java service consumes to manage an asset catalog and update prices. The MVP implementation includes Flyway for MySQL schema versioning, a Kafka consumer for real-time data processing, and ordering guarantees using ticker as the key. An index on the ticker field ensures fast queries. The focus is on establishing an end-to-end flow that works seamlessly, with future improvements planned for unit tests and resilience.
