Awesome GitHub RepositoriesDistributed Atomic Transactions

Seata is a distributed transaction coordinator designed to ensure data consistency and atomicity across microservices. It provides a centralized framework for managing global transactions, preventing partial data updates across different databases and services. The project implements multiple transaction modes to balance consistency and performance. This includes an automatic mode that uses rollback logs to coordinate compensation without modifying business logic, a try-confirm-cancel pattern for resources lacking native ACID support, and a saga orchestration engine for managing long-lived bu

FoundationDB is an ACID-compliant distributed transactional key-value store. It functions as a scalable database engine that ensures strict serializability and data consistency across a cluster of servers using a shared-nothing architecture. The system is distinguished by its multi-region replication capabilities, allowing data to be synchronized across different datacenters for high availability and disaster recovery. It utilizes optimistic concurrency control to manage distributed transactions and employs a majority-based coordination system to maintain cluster state. The platform provides

dtm is a distributed transaction framework and polyglot transaction coordinator designed to maintain data consistency across microservices. It functions as a Saga orchestration engine and a two-phase message coordinator, ensuring that multi-service operations either succeed completely or roll back to a consistent state. The project distinguishes itself by supporting multiple consistency patterns, including Saga, TCC, XA, and outbox patterns, allowing users to select the appropriate model for their specific application requirements. It provides a polyglot integration layer via HTTP and gRPC, e

Hazelcast is a distributed data platform that combines an in-memory data grid with a stream processing engine to support real-time analytics and event-driven applications. It functions as a partitioned, distributed key-value store that replicates data across cluster nodes to provide low-latency access and high availability. The platform also serves as a distributed SQL query engine, allowing users to execute standard SQL statements against both in-memory datasets and external data sources. What distinguishes Hazelcast is its use of a distributed consensus subsystem to maintain strongly consis

Ignite es una plataforma de cómputo y rejilla de datos distribuida en memoria. Funciona como una base de datos SQL distribuida y un motor de almacenamiento diseñado para almacenar y procesar grandes conjuntos de datos en RAM para minimizar la latencia y aumentar la velocidad de cálculo. El sistema se distingue por un motor de almacenamiento de varios niveles que gestiona la ubicación de los datos a través de la memoria y el disco para equilibrar el acceso de alta velocidad con una gran capacidad. Cuenta con una rejilla de cómputo distribuida que ejecuta lógica personalizada directamente en los nodos donde residen los datos para reducir el tráfico de red. La plataforma proporciona un amplio conjunto de capacidades, incluyendo gestión de transacciones ACID, consultas SQL estándar y operaciones de clave-valor. Admite la ingesta de datos de alto volumen a través de flujos reactivos y ofrece integración a través de múltiples lenguajes de programación, controladores de base de datos estándar y una API REST. El sistema puede desplegarse como un clúster distribuido utilizando contenedores u orquestarse mediante Kubernetes. El proyecto está escrito en Java y puede instalarse mediante archivos binarios.

RavenDB is a multi-model NoSQL document database designed for high-performance, ACID-compliant data storage. It persists structured information as schema-flexible JSON documents and utilizes a unit-of-work session pattern to track entity changes and batch modifications into atomic transactions. The platform is built on a distributed architecture that supports horizontal scaling through sharding and ensures high availability via multi-node, master-to-master cluster replication. The database distinguishes itself through a self-optimizing query engine that automatically creates and maintains ind

TinyKV is a distributed key-value store designed for storing and retrieving data across multiple nodes with high availability. It functions as a distributed database system that incorporates a dedicated key-value storage engine for raw data persistence and retrieval on individual nodes. The project includes a Raft consensus engine to ensure data consistency and fault tolerance across a cluster of servers. It also features a distributed transaction manager that coordinates atomic commits and concurrency control to maintain data integrity across shards. The system covers cluster membership man

pgdog is a PostgreSQL sharding proxy, distributed SQL router, and connection pooler. It is designed to enable horizontal data distribution by splitting tables and indices across multiple independent servers to scale storage and processing capacity. The project distinguishes itself through online resharding capabilities, using logical replication to move data between shards without application downtime. It supports multiple routing strategies, including hash, list, and range-based query routing, and manages distributed atomic transactions using a two-phase commit process to ensure consistency
