This article explores RocketMQ's high availability mechanism, focusing on DLedger's implementation of Raft-based leader election for distributed message middleware, covering both traditional and Controller mode architectures.
Bilibili’s high‑performance distributed KV store combines hash and range partitioning, Raft‑based multi‑replica consistency, and a Metaserver‑managed topology of pools, zones, nodes, tables, shards and replicas, offering features such as partition splitting, binlog streaming, multi‑active replication, bulk loading, KV‑storage separation, and automated load, leader and health balancing for reliable, scalable data services.
GooseFS, Tencent Cloud’s distributed caching system for storage‑compute separation, links compute frameworks to underlying storage (COS, CHDFS, COSN) and boosts big‑data and AI workloads by 2‑10× through transparent acceleration, robust master‑worker architecture, Raft‑based HA, tiered caching, and metadata optimizations, delivering up to 50% cost savings and 29% faster compute jobs.
This article explores service governance fundamentals, examines why etcd’s Raft‑based consensus and BoltDB storage make it ideal for large‑scale systems, compares it with ZooKeeper and Consul, and shares Baidu’s practical architecture, performance tricks, and operational metrics for high‑availability, high‑performance service management.
The article details eBay's 2018‑2020 design, performance testing, and fault‑tolerance architecture of a next‑generation core accounting system capable of handling millions of transactions per second, covering system goals, multi‑region deployment, event‑sourcing, Raft consensus, scalability optimizations, and the planned open‑source release.
This article provides a comprehensive introduction to Apache Kudu, covering its origins, cluster architecture with Raft consensus, schema‑based table and partition design, and the intricate storage engine that combines in‑memory and on‑disk structures to deliver fast OLTP and OLAP capabilities on fast data.
CynosDB is Tencent Cloud’s high‑performance, highly‑available NewSQL distributed database that uses a shared‑storage architecture with primary and replica instances, log‑structured storage, RDMA/SPDK transmission, Raft consensus, SSI MVCC, two‑phase locking, and state‑machine replication to provide elastic scaling, fast recovery, and cost‑effective enterprise data management.
