Important

The SingleStore 9.1 release candidate (RC) gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 9.0 is recommended for production workloads, which can later be upgraded to SingleStore 9.1.

SingleStore Flow API

Note

This is a Preview feature.

The SingleStore Flow API allows you to create, configure, and manage Flow pipelines, enabling seamless integration with third-party applications and workflow automation. It provides an HTTP interface that primarily follows REST conventions, while also supporting RPC-style command endpoints for specific operations.

Flow provides two APIs: Ingest API for data transfers up to 10 GB, and XL Ingest API for larger tables.

Additionally, you can use automated scripts to set up source and destination connections, configure schedule, select tables, apply license, and run a full extract with Ingest APIs. For larger tables, the scripts automate sliced data transfers using XL Ingest APIs.

Refer to the Example Flow API Scripts for sample Python and bash applications that use the API.
