Hey, I am doing some experiments with transformer models and I found it extremely easier to work with data stored in SQL database than arrow/parquet files.
It is easier to browse and select, or create subsets for different models and store them in different tables etc.
Is there any good library to use SQL as data source for 
models? Specifically, I am looking for a lightweight solution to link Google Colab to use data from my postgresql database (running on a dedicated host).
