Polars
- handling of categoricals in polars seemed a little underbaked, though my main complaint, that categories cannot be pre-defined, seems to have been recently addressed: https://github.com/pola-rs/polars/issues/10705

Stuff I Learned during Hanukkah of Data 2023
That turned out to be related to pola-rs/polars#11912, and this linked comment provided a deceptively simple solution - use PARSE_DECLTYPES when creating the connection:

Summing columns in remote Parquet files using DuckDB
Looks like somebody requested it after reading your TIL. https://github.com/pola-rs/polars/issues/12493#issuecomment-...
It will be in the next release. (later today?)

What are you rewriting in rust?
I am a maintainer for a dataframe interface called polars

[Crowdsourcing] Is there any code you really wished used named function arguments?
For example with polars, the python library extensively uses named arguments, but in rust we have to use either a builder pattern or macros. The builder pattern tends to be much more verbose than the named argument equivalent. There is currently a draft PR implementing python style named arguments for some of the most common functions.

Working with Rust
Seeing a lot of great libraries coming out with python bindings in the data world e.g delta-rs Polars. I see it growing in this space as a C++ alternative

Google Analytics 4 Has Me So Frustrated, We Built Our Own Analytics Service
In bigger setups, all you want is a data collector and router so that you can feed the data into multiple destinations, depending on the use case. Analytics is just one. Example: https://www.rudderstack.com/ & https://www.rudderstack.com/replace-google-analytics-4-guide...

I want to contribute to open source but don't know where to start
Check out RudderStack, a Go project to build data pipeline. Our slack is quite active. The best way to contribute is by creating a new integration with your favorite tool. You do not need to rely to too much on existing knowledge about inner workings of the project to do so, so it is beginner friendly.

Writing few lines of open-source js/python code can get ₹8k-80k. Is it a good reward for an oss challenge? Last day, more prizes than the participants until now :)
I thought, start the challenge, they will come. I was wrong. This is the last day of the Transformations challenge at RudderStack. If you compare the # of submissions with the # of prizes, there are good chances that your submission may get a prize (lowest ₹8k and highest ₹80k).
The challenge is over. Winners have been announced. When we are ready for the next one, will announce on RudderStack GitHub repo

Entire tech industry right now
P.S. If you're here, do support open-source project - RudderStack
RudderStack?

Go doesn’t do any magical stuff and I love that
RudderStack (open-source event streaming, alternative to Segment) processed 1 trillion+ events last year and has 400+ integrations with different services. It would have been nightmare if it was not built in Go.

Interview Prep - Senior Data Integration role
RudderStack, dbt, Kafka, Headless CDP, etc. on top of my mind

Can we take a moment to appreciate how much of dataengineering is open source?
