What is the 'stor' command in Nushell?

The 'stor' command is a built-in feature in Nushell that allows users to manage an in-memory or file-based SQLite database directly from the command line for fast data operations.

Can I persist data between different Nushell sessions?

Yes, the skill provides patterns for exporting 'stor' databases to SQLite files and using native file formats like NUON to maintain state across shell restarts.

How does this skill handle large datasets?

The skill utilizes Parquet and Polars integration patterns, which allow for columnar storage, compression, and lazy loading of massive data files that exceed memory capacity.

Does this skill support SQL queries?

Yes, it provides guidance on using 'stor open | query db' to run standard SQL queries against your Nushell data tables.

Why would I use NUON instead of JSON?

NUON is Nushell's native format. Unlike JSON, it preserves specific types like dates, durations, and file sizes, making it more robust for shell-specific data persistence.
