This video from VAST Data Customer Education explores the powerful options for accessing and querying the VAST Data Catalog beyond the web interface. For storage administrators and developers, this tutorial is a technical guide to using command-line tools, programming libraries, and external query engines for advanced data analysis and automation. The video details three primary non-GUI access methods: vastdb_cli: Learn about this dedicated CLI utility from VAST's GitHub repository. We demonstrate how it can be used to run simple, targeted queries from the command line, providing a quick way to retrieve information without a graphical interface. Python SDK: For programmatic access, we showcase the vastdb_sdk, which enables you to construct complex queries within a Python script. This is ideal for integrating catalog data into custom scripts, applications, and automation workflows. REST API: We explain how to make direct calls to the VMS REST API for querying the catalog. The video also highlights the vaspy_cli utility as a simple way to format and send these API calls from a shell script, using VMS credentials. The most powerful option for data analysis is the use of external query engines like Trino or Apache Spark. We discuss how these engines can connect directly to the VAST Catalog, leveraging the VAST DASE architecture to perform complex, distributed queries with superior performance and advanced functionality. The video notes that these methods require an S3 access key and a properly configured VIP pool to authenticate and access the catalog database via the client-facing network. This tutorial is designed to provide VAST Data operators with the in-depth knowledge to choose and implement the right method for accessing the VAST Catalog, from simple command-line queries to large-scale, enterprise-level analytics.
