Database choice is downstream of operational maturity, not feature lists.

Distributed SQL database for real-time analytics of time series data

Why consider the swap

If you currently rely on Kdb+ and want more control over data, lower long-term costs, or a open-source licensing model, CrateDB covers most of the same ground.

What you trade off

Most open-source alternatives require more setup than their commercial counterparts and may lag on polish, mobile apps, or ecosystem integrations. Check the project’s documentation for current feature parity with Kdb+ before committing.
