perspective

Try this project I work on, https://perspective.finos.org/ . It comes with a Python library (that runs the exact same engine/code as in the wasm version), and even a JupyterLab plugin. You can run the engine fully in-python, in-Javascript (via wasm), or replicated between the two.

Yes definitely. For example, the perspective pivoting engine (https://github.com/finos/perspective) supports arrow natively, so you can stream arrow buffers from a big data system directly to be manipulated in your browser (treating the browser as a thick client application). It's a single copy from network buffer into the webassembly heap to get it into the library.

Have you seen https://github.com/finos/perspective? Though they removed the JS library a few months ago in favour of a WASM build of the C++ library.

In Perspective (https://github.com/finos/perspective), we use Apache Arrow as a fast, cross-language/cross-network data encoding that is extremely useful for in-browser data visualization and analytics. Some benefits: - super fast read/write compared to CSV & JSON (Perspective and Arrow share an extremely similar column encoding scheme, so we can memcpy Arrow columns into Perspective wholesale instead of reading a dataset iteratively). - the ability to send Arrow binaries as an ArrayBuffer between a Python server and a WASM client, which guarantees compatibility and removes the overhead of JSON serialization/deserialization. - because Arrow columns are strictly typed, there's no need to infer data types - this helps with speed and correctness. - Compared to JSON/CSV, Arrow binaries have a super compact encoding that reduces network transp
