HowToCSV's answer
To ensure privacy and security, all computation occurs client-side, directly on the user's local machine. To achieve this, the entire system uses only client-side technologies, starting with NextJS and extending to WASM modules with in-memory analytics DBs for complex transformations and manipulations: no data ever leaves the user's computer.

"iLovePDF for CSV files": a single place with lots of tiny browser-based utilities for anything you might need to do with tabular CSV data without installing heavy software or writing code. Itโs focused on real quick hacks: merge, unpivot, clean, convert, forecast, generate synthetic scenarios, etc. and all in the browser.

Even if you hate CSVs, you'll love what we can do with them!
Zero installs โ tools run directly in your browser.
Lots of small focused utilities in one place instead of searching for separate converters or editors.

Imo if you are using the cloud and not doing anything particularly fancy the native tooling is good enough. For AWS that is DMS (for RDBMS) and Kinesis/Lamba (for streams). Google has Data Fusion and Dataflow . Azure hasData Factory if you are unfortunate enough to have to use SQL Server or Azure. Imo the vendored tools and open source tools are more useful when you need to ingest data from SaaS platforms, and... Source: over 3 years ago

I am pretty sure they are using pub/sub with probably a Dataflow pipeline to process all that data. Source: almost 4 years ago
You can run a Dataflow job that copies the data directly from BQ into S3, though you'll have to run a job per table. This can be somewhat expensive to do. Source: almost 4 years ago
It was clear we needed something that was built specifically for our big-data SaaS requirements. Dataflow was our first idea, as the service is fully managed, highly scalable, fairly reliable and has a unified model for streaming & batch workloads. Sadly, the cost of this service was quite large. Secondly, at that moment in time, the service only accepted Java implementations, of which we had little knowledge... - Source: dev.to / about 4 years ago
