Streaming Script
Hey everyone,
does anyone have a working script for streaming? I would highly appreciate it. Thank you so much!
Hi @philippe926 , please have a look at this conversation thread where a similar question was asked and an example of how to stream data was given https://huggingface.co/datasets/openclimatefix/dwd-icon-eu/discussions/10, I hope that helps. Just an FYI in general we have found streaming to be slow when done from HF and have in the past moved data we needed (sliced down to what we strictly needed so it's smaller) to quicker storage options e.g. cloud storage or on premise and then streamed from there.
Also just an FYI that soon this data will be available on dynamical.org and this will be in a zarr format optimised for streaming so that could be a good option for you, we will be deprecating the dataset on here after this is done.
Hello!
Has the porting of the historical dataset been completed?
I see dynamical.org shares a small rolling window, like 1.5 months, of live raw data from DWD icon-eu.
But I cannot find the zarr format optimised for streaming of ICON-EU
Thank you
Hi,
Please see the following discussion for updates on the Zarr on Dynamical.org: https://huggingface.co/datasets/openclimatefix/dwd-icon-eu/discussions/14
In short: The Zarr is almost ready, but isn't yet live on Dynamical.org. The Zarr will extend back to 2026-02-10 (when the GRIB archive started).
One small correction to your post: The GRIB archive on Source Co-Op isn't a rolling archive. It's a full archive. It will archive 86 TiB of ICON-EU GRIBs per year. More details in the docs: https://source.coop/dynamical/dwd-icon-grib
yes sorry, I used the wrong terminology. It will be a full archive from 2026-02-10 onwards.
What I meant is that the historical raw data is not available before there.
so this dataset here is still important for modeling on 2025, 2024 and back.
Ok thanks for the info
I will monitor the discussions also on github, I have found this:

Sounds good. You're right that this HuggingFace archive will continue to be relevant.
Also, keep an eye on this GitHub issue, for the latest updates on the conversion to Zarr: https://github.com/dynamical-org/reformatters/issues/173
