Threading / Async BDP / BLP

[mg3146]

Hi all,

I was wondering if anyone else has been able to do threading / async-await with bdp/blp calls?

My current workflow has me calling, in sequential order:
hist_data = blp.bdh(4 tickers , 1 field, start_date = 10 yrs ago)
live_data = blp.bdp(150 tickers, 4 fields)

This sequential call takes about 3.5 seconds to run, split pretty evenly between the two calls.

I was hoping to do something like to speed up the result
`with ThreadPoolExecutor() as executor:

        bdh = executor.submit(blp.bdh, **_bdh)   #  **_bdh = kwargs
        bdp = executor.submit(blp.bdp, **_bdp)   # **_bdp = kwargs
    
        hist_data_df= bdh.result()    
        live_data_df = bdp.result()`

But this is throwing this error in blpapi\exception.py:
UnsupportedOperationException: Attempt access name 'security' on array element 'securityData' (0x00080003)

I'm not sure if its my implementation, or something more deep-seeded going on. Any help appreciated!
