Oracle Database 23c Microservices and Transactions

Oracle Database 23c In-Database Transactional Event QueuesModern applications are being built as microservices.  Many are loosely-coupled services that use asynchronous events on Kafka.  Ensuring that event handlers preserve  data consistency across microservices is difficult and this is where 23c In-Database Transactional Event Queues come in.23c In-Database Transactional Event Queues provide the benefits of ACID and transactions for streaming event platforms like Kafka.This briefing provides an overview of In-Database Transactional Event Queues (TxEventQ). making microservices development simpler for streaming events.TxEventQ provides the following: - Publish/consume of events is transactionally integrated with database changes - Handles complex cases like events that change database state - Provides exactly-once semantics without 2-phase commit and idempotency headaches - Security, backup, recovery of events and data are tied together
