Load Data with SingleStore Flow

On this page

Overview

SingleStore Flow (or, "Flow") is SingleStore's data migration and change data capture (CDC) solution which is comprised of two primary components:

  • SingleStore Ingest, also referred to as "Ingest," transfers the schema for all tables, moves table data for tables up to 10GB in size, and handles ongoing CDC for all tables into SingleStore.

  • SingleStore XL Ingest, also referred to as "XL Ingest," handles the initial transfer of large tables by breaking them into smaller logical partitions. It then copies multiple partitions from the source to the target in parallel. This helps transfer large tables in a reasonable amount of time.

Flow supports the following source databases for transfer to SingleStore:

  • Oracle

  • Microsoft SQL Server

  • MySQL

  • PostgreSQL

  • Snowflake

  • Any JDBC-complaint database (non-production preview, available for testing)
