Real questions. Useful conversations. Find the people who know your stack.
Decide whether Akka Cluster Sharding fits your stateful actor service, with configuration, an Order entity example, and operational trade-offs.
Learn how to prevent slow consumer issues in NATS by implementing JetStream Pull Consumers with explicit acknowledgments for reliable, at-least-once delivery.
Stop hardcoding service IPs. Learn how the Moleculer Service Broker uses transporters and service discovery to provide location transparency and automatic load balancing in microservices.
Stop zombie requests from crashing your system. Learn how gRPC deadline propagation flows through call chains and how to properly implement it to prevent cascading failures.
Learn how to configure NATS JetStream acknowledgment policies and idempotency patterns to achieve exactly-once processing semantics in distributed systems.
Learn how UML Sequence Diagrams make hidden timing bugs visible by modeling asynchronous messages, parallel fragments, and alternative paths before they cause production failures.
Learn how to use UML Sequence Diagrams to visualize asynchronous message flows and identify race conditions in distributed systems using 'par' and 'crit' fragments.
Stop losing messages when subscribers go offline. Learn how to use NATS JetStream to implement durable streams and at-least-once delivery guarantees.
gRPC deadlines let clients set an absolute expiration time that propagates across service boundaries, preventing zombie requests and cascading failures. Learn how to implement them in Go and avoid common pitfalls.
