Install SingleStore Flow

On this page

This section contains instructions for installing Ingest and XL Ingest, and license information.

To use Ingest and XL Ingest, install the products and provide the product IDs to either team@singlestore.com or your account representative to obtain either a paid license or a Developer trial license.

Prerequisites

While the database prerequisites will vary based on the source, the following are the minimum requirements for using both Ingest and XL Ingest.

Component	Requirements
Virtual Machine (VM)	The sizing recommendation is based on the size of databases/tables being transferred. For smaller databases sized 100GB or less, a minimum of 2 vCPUs, 8 GB RAM, and 100 GB of free disk space is recommended. For large transfers, more disk space may be required. The required free space for Ingest is twice the size of the largest table to be transferred. For very large tables, where XL Ingest must be used, the amount of local disk needed is `2 x (logical partition size) x (number of concurrent partition transfers)`. More CPU cores and RAM is required for sources and destinations that contain a large amount of data and have an aggressive timeline in which to transfer it. The VM must be close to the source database to minimize latency. Refer to the Recommended Hardware Configuration section in the Ingest documentation for more information.
Browser	A Chromium-based browser, such as Google Chrome or Microsoft Edge, installed on the VM
Java	Amazon Corretto Java 21, a no-cost distribution of the Open Java Development Kit (OpenJDK), installed on the VM
