ByConity is an open-source cloud-native distributed SQL data warehouse built on the ClickHouse 21.8 codebase, developed by ByteDance/Volcano Engine. It targets interactive and ad-hoc analytical queries at massive scale with storage-compute separation and deployment on Kubernetes with S3 object storage. The project has been retired: it entered a transition period on June 1, 2026, and the repository will be archived read-only after August 1, 2026, with no new features, bug fixes, or security patches thereafter.

Use cases

run a cloud-native OLAP data warehouse on Kubernetes with S3 storage
serve sub-second interactive and ad-hoc analytical queries over massive datasets
unify offline batch and real-time streaming data ingestion for analytics
query a ClickHouse-compatible warehouse with tools like Superset and Tableau
perform multi-table associative analytical queries with a CBO/RBO optimizer
self-host a Snowflake-like lakehouse analytics engine

When to choose

you already run ByConity and need to keep an existing deployment stable through migration
you need a ClickHouse-compatible engine with storage-compute separation and can accept an unmaintained codebase
you are studying cloud-native data warehouse architecture for research or reference

When to avoid

you need a actively maintained data warehouse with security patches and new features
you are starting a new analytics project with no existing ByConity investment
you require long-term community support or a one-to-one open-source replacement
