TiDB’s next‑generation tiered storage separates hot data on local SSDs from cold data on object storage, using multi‑tree LSM, segment caching, and IA Manager to reduce storage costs by up to 50 % while preserving low latency for frequent accesses and providing clear migration and monitoring guidelines.
Fifteen years after an internship at Nanda Tongyong, the author returns as an external expert to reflect on personal growth, the evolution of the GBase product line—from the early MPP database to AI‑native HTAP solutions—highlighting technical innovations, benchmark results, and the broader impact on the domestic database ecosystem.
This article presents a step‑by‑step demonstration of using the OpenClaw AI agent to deploy a minimal TiDB v8.5.5 cluster, modify root and create a dbadmin user, run sysbench/TPCC performance tests, and evaluate the feasibility of AI‑driven production‑grade database operations.
Engula is a Redis‑compatible, high‑performance in‑memory database that cuts memory usage by up to 50% through compression and metadata optimization, while incurring only about 10% performance overhead, and its architecture, testing methodology, and benchmark results are detailed in this article.
The article reviews MongoDB 8.2’s major upgrades, highlighting up to 36% read throughput gains, 59% write speed improvements, 200% faster time‑series aggregation, 50‑fold faster shard rebalancing, enhanced queryable encryption, native vector search, multi‑cloud Atlas support, and AI‑driven capabilities such as hybrid search and the MongoDB AMP platform.
In a landscape crowded with OLTP, OLAP, HTAP, NewSQL and cloud‑native options, this article explains why enterprises must look beyond performance and assess a database’s five‑dimensional long‑term service capability to ensure sustainable growth and low migration risk.
This article explains the structure and resources of the MongoDB global community, details the elite MongoDB Champions program, outlines how to become a Champion, and highlights the professional and technical benefits of participation for developers and database professionals.
At DTCC2025 in Beijing, industry leaders showcased AI-driven innovations, vector database advances, RAG techniques, and distributed database performance breakthroughs, illustrating how databases are evolving from passive data stores into intelligent, autonomous systems that boost efficiency, scalability, and business value across sectors.
Zhihu’s evolving data architecture transitioned from a single MySQL setup to a heterogeneous ecosystem of SQL, NoSQL, and graph databases, ultimately adopting OceanBase for its multi‑tenant, high‑compression capabilities, supported by tools like OMS, OCP, and ob‑operator to achieve cost savings, performance gains, and robust operations.
This guide walks developers through downloading, installing, and using OceanBase Desktop on macOS, covering dependency setup with OrbStack, GUI features, cluster startup, tenant management, and how the tool simplifies local OceanBase cluster deployment.
