Show HN: Hashquery, a Python library for defining reusable analysis
11 by cpimhoff | 0 comments on Hacker News.
Hi all, we recently open sourced the first version of Hashquery, a Python library which lets you model analytics, DRY up common logic, and execute it against a database or warehouse. We were originally rendering SQL directly for all our queries, but that spiraled out of control with more complex analysis; the SQL needed to be changed sporadically for each new database dialect (BigQuery, Redshift, Aethena, Postgres, etc etc) and the SQL fragments were very challenging to reuse (and so fragments were copy-pasted all over). ~~~ Advantages we think it has over writing SQL by hand: - Queries are fully compossible, so any analysis can be chained into further analysis without refactoring. - All analysis executes within the data warehouse itself, making them super fast for big data. - It's just Python, so you can extend or parameterize query logic with a simple def function. - You can run it anywhere, like inside of unit tests, ETL nodes, or Jupyter notebooks. - Developer experience is pretty good since editors already know how to autocomplete Python. ChatGPT knows Python already too :) - The library handles normalizing between database dialects. Write once and use in any database. - Hashquery content is fully serializable, which makes it a good fit for exposing a flexible API for consumers to efficiently query datamarts or internal analytics. We use it as the endpoint for headless BI, as opposed to having to define and teach a DSL or GraphQL specification. ~~~ We've built native funnel analysis on top of Hashquery and have been thrilled with it so far, and we thought others might want to use it too. It's pretty early days so we're still trying to explain it, and the docs aren't perfectly clear, but the examples on the dev site are editable and you can download the pip package to play around with it!
