Description

In scikit-learn, we were about to bring a simple new ARFF parser based on pandas.read_csv. In short, it skipped the header, read the dataset and cast the nominal columns (we don't really care about the datetime format). It is from x4-x10 faster and take x2 less memory.

However, we now wonder if we should indeed integrate this parser since it could become obsolete. Basically, it would depend on the timing regarding making the dataset available in parquet format through the OpenML site. I saw in some previous issue that it could be available soon.

Do you have an estimate (even rough) of the timeline for the feature to land?

Research direction

The issue is a timeline question about making datasets available in Parquet format through OpenML. It names no files, tests, or entry points to inspect, and does not define an implementation task or completion criteria; first clarify the feature's status and scope before attempting work.
