What it is

GlassFlow is the only open-source streaming ingestion & data transformation system for ClickHouse. It's highly scalable, provides native connectors, and supports stateful transformations, making your ClickHouse faster, cheaper, and easier to manage.

What to verify before adopting

• Confirm current pricing, usage limits, supported regions, and contract terms on the official website.
• Test integrations, export paths, access controls, and failure recovery with low-risk data first.
• Review privacy, data retention, security, and compliance requirements for your market.
• Keep a migration or rollback plan before making the product part of a critical workflow.
