GoldenDB, co‑developed by ZTE and CITIC Bank, is a PGXC‑based distributed database that delivers strong consistency, flexible sharding, high performance, MySQL compatibility, and comprehensive management tools, making it especially suitable for demanding financial industry workloads.
The article explains the principles, implementation techniques, trade‑offs, and typical use cases of strong consistency and eventual consistency in distributed systems, helping architects decide which model best fits the performance, availability, and correctness requirements of their applications.
This article explains the Paxos consensus algorithm, detailing its roles (proposer, acceptor, learner), the two-phase prepare and accept process, handling of proposal numbers, and how it ensures strong consistency across distributed nodes through examples and diagrams.
This article explains the motivations behind distributed databases in high‑risk industries, introduces Tencent Cloud's TDSQL as a market leader, and details its architecture—including load balancing, SQL engine, compute and storage separation, raft‑based strong consistency, lossless upgrades, high‑availability failover, and an intelligent DBA platform.
The article introduces Deno KV, a globally replicated, strongly consistent key‑value database that runs locally with SQLite or in Deno Deploy with FoundationDB, highlights its simple yet powerful JavaScript‑centric API, atomic transactions, consistency models, and provides practical code examples for developers.
This article explains the concept of consistency in distributed transactions, compares strong and weak consistency, relates it to the CAP theorem, and explores theoretical and practical approaches—including XA, NewSQL, and MVCC—to achieve stronger consistency across databases and micro‑services.
This article explains ByteKV's design—using range partitioning, a custom Raft implementation, multi‑layer architecture, and advanced load‑balancing strategies—to provide strong consistency, flexible data models, and seamless scalability for large‑scale storage workloads.
This article explains how Tencent's TDSQL database tackles the combined challenges of transaction and distributed consistency by introducing a multi‑level strong consistency model that delivers several‑fold performance improvements over Spanner, CockroachDB, and native Greenplum while preserving ACID guarantees.
The article details the three‑stage evolution of 58.com’s distributed key‑value storage system WTable, covering its initial architecture, performance and operational optimizations, and the introduction of NewSQL‑style strong consistency and Raft‑based replication to improve scalability and reliability.
The article examines how to achieve data consistency in distributed internet systems by comparing strong and eventual consistency, detailing local database transactions, two‑phase commit protocols, rollback mechanisms, local message tables, and compensation strategies, and discusses their trade‑offs and suitable application scenarios.
PhxSQL is an open‑source, MySQL‑compatible relational database cluster that provides high availability and strong data consistency through a single‑master multi‑slave architecture, automatically switching masters when over half the nodes are alive, without relying on external services like Zookeeper, and requiring no code changes for migration.
