This guide explains all the steps to install the Analytics Toolbox in your Databricks enviroment.
The CARTO Analytics Toolbox contains two packages:
- core: this is the public and open-source package.
- advanced: this is a premium package. It contains the Tiler module, that allows to process and visualize very large spatial datasets stored in Databricks.
To install the core package of the Analytics Toolbox in your Databricks cluster, follow the instructions below on your Databricks workspace UI:
- Click on Compute
- Select the cluster where you want to install the Analytics Toolbox
- Open the Libraries tab
- Click on Install new
- Select Maven as Library Source
- Click on Search Packages, select Maven Central and look for
carto.analyticstoolbox; select the latest version of the one that their “Artifact Id” start as “core_” (the other one is a dependence that this one install under the hood, you do not need to install the package that their “Artefact Id” start with “hiveless”).
- Click on Select
- Click Install to finish the process. Dependencies of the package will be installed transitively
