StarRocks is an open‑source project under the Linux Foundation, focused on building a high‑performance, scalable analytical database that enables enterprises to create an efficient, unified lake‑house paradigm. It is widely used across many industries worldwide, helping numerous companies enhance their data analytics capabilities.
This article explains the concept of a metrics layer, why StarRocks is suited for building such platforms, and presents detailed case studies from Airbnb, a major bank, and a leading restaurant chain, while comparing three modeling paradigms and outlining the future vision for materialized views.
This article details the challenges of maintaining separate real‑time and batch risk‑control features, evaluates Lambda and Kappa architectures, explores storage‑unified and compute‑unified alternatives, compares Hologres, StarRocks and ClickHouse, and presents a validated StarRocks‑based solution that dramatically reduces feature delivery latency and improves accuracy.
The article details how the Xiaohongshu data warehouse team integrated StarRocks into their offline processing pipeline, replacing Spark for heavy Cube calculations, which reduced job execution from hours to minutes, cut resource consumption by over 90%, advanced daily data output by 1.5 hours, and lowered refresh cost by more than 99%.
This article explains how Ping An Bank transformed its retail finance model from product‑centric to customer‑centric using a five‑in‑one data‑driven approach, the KYC/KYP/KYATO methodology, and the StarRocks analytics platform to build the Smart Bank 3.0 architecture, CDP, and real‑time metric layers.
This guide walks you through using StarRocks—covering effortless expression‑based partitioning, streamlined data loading with INSERT FROM FILES and PIPE, powerful in‑flight data transformation using SELECT/JOIN/UNNEST, and flexible table structure tweaks via ALTER TABLE to boost query performance.
In this interview, graduate student Sun Yinzhen shares how he selected, designed, and implemented an ORC Chunk Writer for the StarRocks database during the Open Source Summer program, detailing the technical challenges, learning outcomes, and his perspective on open‑source contributions for computer science students.
StarRocks’ materialized view feature lets Didi replace costly fuzzy deduplication with precise, high‑concurrency deduplication for real‑time dashboards, using global dictionary mapping, layered ODS/DWD/ADS views, synchronous and asynchronous refreshes, and transparent query rewrite to cut query latency by 80% and boost QPS dramatically.
This article explains how Apache InLong provides automatic, secure, high‑performance real‑time data transfer to StarRocks, detailing the transactional Stream Load API, the two‑phase commit process, Flink‑based ingestion architecture, exactly‑once guarantees, and performance test results across different parallelism levels.
In 2022 Tencent's A/B Test team created the overseas SaaS product ABetterChoice, abstracting internal experiment capabilities, adapting to multi‑cloud compliance, and unifying computation with StarRocks, enabling game titles like Honor of Kings, PUBG Mobile, and Ubisoft to run scalable, compliant A/B experiments worldwide.
Xiaohongshu’s OLAP team migrated from Presto to StarRocks, doubling cluster count to 30, boosting query speed by 6‑7 times, cutting latency to 200 ms, and achieving up to 35% cost reduction through gray‑scale migration and AWS Spot‑based elastic scaling.
