About the MapD Rendering Engine category


This category is for topics related to usage of the MapD Core Rendering Engine.

Our rendering engine uses the server-side GPUs of a MapD Core database instance to render granular visualizations of large datasets. Users can use the Vega API to specify how to map data (results of a SQL query) to visual attributes as described here. The rendering occurs directly on the same GPU where the data resides, eliminating the need for a costly copy of the result data to the host CPU. The server can then send the client a compressed image rather than the raw data, avoiding a costly network transfer.
