What’s new in version 2.2?

🔍 Advanced filtering in Data Discovery

Data Discovery now offers a significantly more powerful filtering experience through a new filtering panel and expanded modifier controls. Users can access more of SlashDB’s API filtering capabilities directly from the web interface, making it easier to refine datasets without manually building request paths.

The new experience is designed to make advanced filtering more discoverable and more practical in day-to-day work. It supports:

Column match to value (whole and partial)

Logical (AND, OR, NOT) for precise multi-value filtering

Traversal across related tables while preserving filtering logic

Column selection within result sets

Result modifiers, including distinct, streaming, transposing and record count

Table headers now feature a context menu for hiding columns, adjusting sort order and opening advanced filtering.

🦆 DuckDB support for analytical workdloads

SlashDB 2.2 adds DuckDB as a fully supported database backend. This opens the door to new analytical and embedded use cases built on one of today’s most popular open-source analytical databases. Teams can now expose DuckDB-based data through SlashDB’s API and web interface just as they do with more traditional relational backends.

📦 Local installation on Windows

Developers and data engineers can now install SlashDB with standard pip workflows on Windows workstations, include only the database and feature dependencies they need, and use the new init and serve commands to get local instances up and running more quickly.

These packaging and CLI improvements make SlashDB easier to evaluate, faster to prototype with, and simpler to integrate into modern Python-based development environments. Below is an example of launching SlashDB on Windows with support for Microsoft SQL Server and PostgreSQL databases in just a few keystrokes.
