This article explains core cluster concepts, the benefits of building database clusters, classifies common cluster types, and compares scalable architectures such as Oracle RAC, MySQL Cluster, sharding, CAP/BASE theory, and cross‑database transaction strategies for high availability and performance.
This article details a two‑stage approach for creating a geo‑distributed active‑active infrastructure for large‑scale games, covering a pseudo active‑active design with private lines and smart DNS, followed by a true active‑active solution using Redis Sentinel and MySQL clustering with performance comparisons.
This article reviews three mainstream MySQL clustering solutions—MHA master‑slave replication, Oracle's MySQL Cluster, and Alibaba's open‑source Cobar—detailing their architectures, advantages, drawbacks, and practical deployment considerations for high availability and scalability.
This article introduces MySQL Cluster, an in‑memory, real‑time, ACID‑compliant distributed database, explains its multi‑master architecture, data, application and management nodes, transparent partitioning, NoSQL APIs, and presents a benchmark achieving 200 million queries per second on up to 32 nodes.
