Use Flow on Helios

On this page

Flow on Helios is a fully managed data migration and Change Data Capture (CDC) service within SingleStore Helios. It supports loading and synchronizing data from supported databases into SingleStore, without the need to install or manage any infrastructure. Flow is integrated into the Cloud Portal as a part of the Load Data workflow.

It includes two components:

Ingest: Transfers schema and data for tables up to 10GB, and supports ongoing CDC.
XL Ingest: Handles larger tables by partitioning them and transferring partitions in parallel.

Supported Source Databases

The following databases are supported as sources:

MySQL
PostgreSQL
Oracle
Microsoft SQL Server

These can be self-hosted, or hosted on:

AWS RDS
AWS Aurora

Note: On-premise and self-hosted sources must be accessible over the internet and allow inbound connections from Helios IPs.

For prerequisites and setup, refer to Source Database Setup.
