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

kafka helper library

High abstraction wrapper for Golang Rabbit MQ Client

AI-powered inspector and intelligence platform for Azure Service Bus

A fault-tolerant distributed job scheduler that delivers priority-based execution, tenant-aware fairness, and resilient checkpointed workloads with leader-elected high availability.

Self-hosted Kafka UI with free-text search across topics (substring + JSON dotted-path), real-time consumer-lag charts, DLQ flow visualization, and reprocess-only DLQ writes. Solves kafka-ui's exact-match search limitation.

OPS Agent will help you to analyze and debug ops (live operations) issues.

Simple project in Java with Spring Boot demonstrating the producer-consumer pattern using RabbitMQ for asynchronous message exchange, with Docker to facilitate the environment.

Triage records in Kafka dead letter queue (DLQ) topics

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 code for DLQ Algorithm in R

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

Zyven is a reliability middleware that sits between your application and external webhooks to guarantee delivery, retries, visibility, and recovery.
