Show HN: Turn any data into a fast analytical API
we use our in-house baked engine - open sourced here https://github.com/varchar-io/nebula
Yeah, Tinybird has lots of similarities, I will do more research on it, thanks for the reference.

How would you build a BI platform that delivers "real time" insights to users on their smartphones and computer devices in a company of about 200 people?

Streaming multi-file SQL and CSV/TSV/etc., native/WASM and fastest CSV parser
cool - I also hand crafted a CSV parser following RFC4180 a while ago, not sure if you have a repeatable way to benchmark the performance difference?

How is Elasticsearch similar to MongoDB in terms of data storage and usage?
Many modern data systems are designed in a similar way - extract, index, and query in including many low-latency real-time analytical systems, such as clickhouse, druid, pinot, nebula. Take nebula (https://github.com/varchar-io/nebula) as an example - it connects real-time storage engines like Kafka, cloud storage, or pubsub systems, extracts and index data from message queue into its own distributed system, providing low latency query on top of it for business use cases.

The Design Philosophy of Great Tables (Software Package)
Why do you want to render to canvas?
Perspective seems to be the most performant html table. It is more focused on extremely fast updates than styling, although it looks good.
Glide is a newcomer that also renders to canvas.

Show HN: WhatTheDuck – open-source, in-browser SQL on CSV files
SQL workbench also uses https://perspective.finos.org/ for tables. It's a WASM table library which pairs nicely with duckdb and works well with large tables.

Yes. We are working on adding support for aggregation and pivoting using https://github.com/finos/perspective

Show HN: DataSheetGrid, an Airtable-like React component
I haven't looked extensively at react-datasheet. It looks like it is trying to build more of a full product than the other data tables.
I have used ag-grid extensively, its an impressive product. Some pieces are a little awkward to use, particularly auto-sizing. But generally ag-grid has thought of most functionality and has a solution. The creator of ag-grid had a great interview on Javascript Jabber [1].
The other serious data table component that I have seen is FinOS Perspective [2]. This is extremely high performance, also more specialized and probably harder to customize. I think Perspective renders to a canvas element from Rust/C++ compiled to WASM (not 100% sure). It is also made for streaming updates.
AG-Grid supports streaming updates... but only in the commercial version.
Eventually the data model for these types of tables becomes tricky. I will be investigating parquet-wasm for my use case. Hit me up if you want to collaborate.

ChDB: Embedded OLAP SQL Engine Powered by ClickHouse
Something like https://github.com/finos/perspective ? We use an OLAP(-y) WASM engine to provide query-ability to our data visualization tool, and doing the calculations in the browser is cheaper and simpler than a server-side database for datasets that fit in browser memory.
