Mesh Datasets is a new query engine introduced by Census that enables SQL queries to span across multiple data warehouses, allowing seamless integration of datasets from platforms like Snowflake, BigQuery, and Databricks without data duplication or complex pipelines. This innovative approach allows data teams to leverage their existing SQL knowledge to create unified datasets that can be activated across various platforms, enhancing data flexibility and utility in a multi-cloud environment. Unlike traditional data virtualization solutions, Mesh Datasets are designed for efficient cross-warehouse SQL execution, ensuring compatibility and performance while simplifying the process of building comprehensive data insights without the need for data consolidation. This tool is available to users who have connected multiple SQL sources to Census, and it includes an AI assistant that helps generate cross-source queries, offering a powerful solution for companies using diverse data stacks to gain a holistic view of their data landscape.
