A sample of non-blocking retries and dead letter topics (aka reliable reprocessing and dead letter queues) with Apache Kafka using Spring Boot and Spring Kafka.
CLI to bring your messages back from SQS Dead Letter Queues.
Coding challenge w/ resilient,high availability and consistent patterns w/ robust deploy strategies using SQS, DynamoDB, Spring, OpenTelemetry, Karpenter, Istio, k8s and Grafana Stack
Spring RabbitMQ Dead Letter Queue (DLQ) Example
A fault-tolerant distributed job scheduler that delivers priority-based execution, tenant-aware fairness, and resilient checkpointed workloads with leader-elected high availability.
OPS Agent will help you to analyze and debug ops (live operations) issues.
Production code for DLQ Algorithm in R
Example (template) project demonstrating how to integrate Apache Kafka with Spring Boot in a modern Java application.
A Go service that consumes order events from Kafka (Redpanda), validates them, stores them in PostgreSQL, and serves them via an HTTP API and a simple web UI. It includes an in‑memory cache with warm‑up, a DLQ for invalid/failed messages, a test data producer (valid/invalid), Prometheus metrics, and OpenTelemetry tracing.
This repository demonstrates how to handle Kafka Consumer exceptions in a non-blocking manner using retry topics and DLQ (Dead Letter Queue).
A set of scripts that help with DLQ message processing
Reliable webhook delivery service with retry logic, exponential backoff, DLQ, and delivery tracking. Built with Node.js, BullMQ, and PostgreSQL. Ideal for backend systems needing robust async communication.
Production-ready NATS JetStream bridge for Ruby/Rails with outbox, inbox, DLQ, and overlap-safe stream provisioning.
