The ByteDance Data Platform team empowers all ByteDance business lines by lowering data‑application barriers, aiming to build data‑driven intelligent enterprises, enable digital transformation across industries, and create greater social value. Internally it supports most ByteDance units; externally it delivers data‑intelligence products under the Volcano Engine brand to enterprise customers.
In a slow‑growth economy, Haidilao’s 30‑year‑old digital transformation—driven by people‑centric change, strategic data investment, and AI‑powered analytics—enables continuous cost reduction, innovation‑led growth, and ultra‑responsive, personalized customer experiences.
Enterprises face a sharp paradox: despite exploding data volumes, only about 20% of structured data is used while the remaining 80% of unstructured data stays frozen, and this talk explores how Data Agent‑powered imperfect AI can awaken that hidden value.
ByteHouse’s BlendHouse, a cloud‑native vector database system presented at ICDE 2025, won the Best Industry and Application Paper Award, showcasing a high‑performance, universally designed framework with deep mixed‑query optimization that outperforms dedicated vector databases in read/write speed and supports large‑scale multimodal retrieval.
ByteDance Data Platform’s recent breakthroughs in database research—spanning query‑level Bayesian tuning, adaptive stream‑processing parallelism, and learned cardinality estimation—were highlighted by two papers accepted at VLDB 2025 and ICDE 2025, showcasing significant performance gains and real‑world deployments.
In today's fast‑changing market, traditional intuition‑based decisions falter, but systematic A/B testing—illustrated by ByteDance’s academic‑loop culture and real‑world case studies—empowers organizations to replace guesswork with evidence, accelerate innovation, and achieve measurable performance gains across products and strategies.
This article examines the hidden complexities of A/B experiments in short‑video recommendation feeds, explains why traditional designs produce biased results due to learning, double‑sided, and network effects, and presents practical double‑sided and community‑randomized experiment frameworks to obtain unbiased strategy evaluations.
This article explains how ByteHouse integrates high‑performance GIS capabilities into its OLAP engine, describes its spatial indexing architecture, showcases benchmark results against ClickHouse, StarRocks, PostGIS and DuckDB using the NYC Taxi dataset, and outlines when to choose ByteHouse versus other spatial database solutions.
Douyin Group’s data asset management platform introduces a systematic "manage, find, use" approach that unifies metadata collection, full‑coverage data lineage, and a suite of applications across development, governance, asset utilization, and security, while outlining its architecture, modeling, quality metrics, and future roadmap.
This article explains how Douyin Group tackles massive data volume, quality, and efficiency issues by building a four‑layer intelligent platform, standardizing metric management, automating metric decomposition, and creating reusable metric services that boost agility, stability, and cross‑team collaboration.
Volcano Engine’s DataLeap platform offers a unified API service solution that transforms raw data into reliable, secure data services, featuring full lifecycle management, monitoring, permission control, rate limiting, and visual API orchestration to simplify complex data workflows and improve operational efficiency across big-data scenarios.
