Open multiple json urls

This is a parallelized version of open_json. Use a Threads Pool by default for parallelization.

  • urls (list(str)) –

  • max_workers (int) – Maximum number of threads or processes.

  • method

    The parallelization method to execute calls asynchronously:
    • ’thread’ (Default): use a pool of at most max_workers threads

    • ’process’: use a pool of at most max_workers processes

    • (XFAIL) Dask client object: use a Dask distributed client object

    Use ‘seq’ to simply open data sequentially

  • progress (bool) – Display a progress bar (True by default, not for dask client method)

  • preprocess ((callable, optional)) – If provided, call this function on each json set

  • url_follow (bool, False) – Follow the URL to the preprocess method as url argument.
