Hello, I will build the Vert.x microservice with reactive endpoints, WebSocket real-time updates, PostgreSQL persistence, and OpenAPI-annotated routes, following your event-bus patterns and delivered with Dockerfile, compose config, and full tests. For non-blocking DB access, I will use vertx-pg-client instead of JDBC. It runs on the event loop without worker threads , a single blocking JDBC call under load stalls the verticle and breaks WebSocket delivery to connected clients. Questions: 1) Is the event bus local or clustered (Hazelcast/Infinispan)? 2) Should updates fan out to all clients, or only subscribers of specific resource changes? 3) Shared PostgreSQL across services, or does each service own its database? Looking forward to your response. Best regards, Kamran

Hi there, We will build the Vert.x microservice with reactive endpoints, WebSocket streaming, PostgreSQL persistence, and OpenAPI-annotated routes, integrated into your event-bus architecture with Dockerfile, compose setup, and tests. We will use vertx-pg-client with prepared-statement caching on the pool. This eliminates parse/plan overhead on repeated queries and keeps throughput stable as WebSocket connections grow, JDBC would block the loop and stall delivery. Questions: 1) Is the event bus local or clustered (Hazelcast/Infinispan)? 2) Should updates broadcast to all clients, or only to specific resource subscribers? Send me a message and we can go over the details. Best regards, STALLYONS Technologies
