Important

Helios features are now enabled during weekly update windows and are no longer directly tied to SingleStore engine releases. Refer to the release notes to view the latest features available in your Helios cluster.

Free Trial Access to Flow

SingleStore Flow is available without a license for learning and development purposes. It is not intended for production use.

With the no-license operation, the total data transfer is limited to:

Ingest: 10 million rows or 10 GB, whichever comes first.
XL Ingest: 10 million rows, with up to 3 slices.
SingleStore destination capacity: Up to 1 unit.

This limit applies to all types of data transfer, including both initial extracts and change data capture (CDC) operations. The enforcement of this limit is on a best-effort basis and may not be exact.

If you require production use or higher data transfer capacity, please contact us to request a license.
