    Nice blog  !!


    I have one suggestion:

    Instead of copying the weather table into the kdb memory space, you can pass the weather PyKX object to kx.q.sql like so:


    >>> weather = kx.q.read.csv('./abr_meteo23.csv', types='IIII****' + 'FS'*24, delimiter=';', as_table=True) >>> ## kx.q['weather'] = weather
    >>> kx.q.sql('select STATION, count(distinct(MAGNITUDE)) from $1 group by STATION', weather)
