Add load from parquet

[info-rchitect]

Hi,

pandas natively supports loading parquet files. This is orders of magnitude faster, getting more improvement as file size and column counts grow. Can this be added as a new feature?

thx

So I currently support loading parquet files programmatically using dtale.show_parquet(path=...) but I will work adding the ability to load parquet files using the "Load Data" popup in the UI.

I'll also add the ability to export your data to parquet files. Currently you can only do CSV or TSV.

Thanks @aschonfeld, will try out the API and see how it performs.
