AWS Data Wrangler

9 3,797 9.4 Python

pandas on AWS - Easy integration with Athena, Glue, Redshift, Timestream, Neptune, OpenSearch, QuickSight, Chime, CloudWatchLogs, DynamoDB, EMR, SecretManager, PostgreSQL, MySQL, SQLServer and S3 (Parquet, CSV, JSON and EXCEL).

Project mention: Read files from s3 using Pandas/s3fs or AWS Data Wrangler? | /r/dataengineering | 2023-12-06

I had no problem with awswrangler (https://github.com/aws/aws-sdk-pandas) and it supports reading and writing partitions which was really helpful and a few other optimizations that made it a great tool

functime

5 891 9.6 Python

Time-series machine learning at scale. Built with Polars for embarrassingly parallel feature extraction and forecasts on panel data.

Project mention: functime: NEW Data - star count:616.0 | /r/algoprojects | 2023-11-08

WorkOS

workos.com sponsored

The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
awkward

4 792 9.6 Python

Manipulate JSON-like data with NumPy-like idioms.

Project mention: Efficient Jagged Arrays | news.ycombinator.com | 2023-07-03

there's a whole ecosystem in Python originally developed for high energy physics data processing: https://github.com/scikit-hep/awkward all because Numpy demands square N-dimensional array
Same technique used everywhere, here's a simple Julia pkg for the same thing: https://github.com/JuliaArrays/ArraysOfArrays.jl/blob/3a6f5b...
But Julia at least has the decency to just support ragged Vector{Vector} out of the box, and it's not that slow

lonboard

1 385 9.5 Python

Python library for fast, interactive geospatial vector data visualization in Jupyter.

Project mention: Parquet-WASM: Rust-based WebAssembly bindings to read and write Parquet data | news.ycombinator.com | 2024-04-22

I'll let Kyle chime in but I tested it a few months ago with millions of polygons on an M2 16GB of RAM laptop and it worked very well.
There is a library by the same author called lonboard that provides the JS bits inside JupyterLab. https://github.com/developmentseed/lonboard
I think it is based on the Kepler.gl / Deck.gl data loaders that go straight to GPU from network.
