Build Automated Workflows with Live Impala Data in Workato

Workato is a cloud-based automation platform that helps businesses integrate applications and automate workflows. When paired with CData Connect AI, you get instant, cloud-to-cloud access to Impala data for visualizations, dashboards, and more. This article shows how to connect to Impala and build workflows with live Impala data in Workato.

CData Connect AI provides a pure SQL Server, cloud-to-cloud interface for Impala, allowing you to easily build visualizations from live Impala data in Workato. As you build automations, Workato generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc) directly to Impala, leveraging server-side processing to quickly return Impala data.
