Presto

Presto is an open-source distributed SQL query engine designed for fast analytic queries against data of any size. It's particularly well-suited for querying large data sets distributed across multiple heterogeneous data sources.

Timbr + Presto Logo

Integrating Presto with Timbr combines the strengths of both platforms. It allows you to use Timbr's semantic graph capabilities alongside Presto's powerful distributed query processing features. This integration enhances your ability to perform semantic querying, data virtualization, and integrated data management across diverse data sources, leading to faster insights and more efficient data operations.

Getting Started with Presto​

If you haven't yet connected to a Presto cluster, follow these steps to set up and establish a connection:

To connect Timbr to your Presto datasource, you need to use the Presto JDBC driver. For information on the Presto JDBC driver and how to set it up, refer to the Presto JDBC Driver documentation.

Connecting Timbr to Presto in the Timbr Platform​

Once you've set up a Presto cluster and have the JDBC driver ready, it's time to connect Timbr to Presto. Follow the steps below for a detailed tutorial on connecting Timbr to Presto:

  1. Navigate to Manage Datasources: From the Timbr interface, click on the Manage tab and select Datasources.

  2. Add New Datasource: On the top right, click the Add New Datasource button. Alternatively, you can click the big add button beneath the knowledge graphs and datasources tabs.

Add new datasource

  1. Fill in Connection Details: A pop-up window will appear where you need to provide the relevant connection details to connect Presto to Timbr.

There are two options in Timbr to enter the connection information: Simple or JDBC Url.

On the top right of the pop-up window , the toggle can be switched from Simple to JDBC Url in order to connect the datasource using the relevant JDBC URL.
