Jan 1, 2025January 2025 monthly summary for ClickHouse/clickhouse-docs focusing on documentation-driven improvements that enable scale, upgrades, and cost visibility. Delivered Make Before Break (MBB) scaling and upgrade mechanism documentation, including planning migrations, upgrade workflows, and a new compute–compute separation section to clarify resource isolation. Improved backups, cloud storage, and backup pricing documentation to reflect policies, costs, BYOB usage, and Azure export status. Clarified AWS PrivateLink availability and tightened security doc formatting to enhance user understanding. Updated billing and pricing policy guidance to cover new dimensions (data transfer, ClickPipes) and clarify legacy pricing notes. While there were no major code fixes this month, these documentation and policy efforts reduce operational risk, shorten onboarding, and improve cost transparency and upgrade readiness.
