Hi all,
I have been wondering recently, with the new Board API functions, is it possibe to use it to read data from a Board database to another, or within the same database (to manipulate data through mapping and / or ETL functions that would not be possible through dataflows) ?

If yes, how would you do that ?

Thanks,

Etienne

    Hi @Etienne CAUSSE,

    I don't think I fully understand your request.
    What would be different if you'd use extract and re-import via flatfiles?
    The only thing I can think of would be the use of an external ETL tool to manipulate your data and then - why not do the proper ETL manipulations before loading data into Board?
    Could you please shed a bit more light on your use case?

    Kind regards,
    Helmut

    Hi @Helmut Heimann,
    You are right, this would be equivalent to an export/reimport, except I have some cases with very large volumes (>10M records with 8 to 10 dimensions) and I am wondering if doing this fully in memory through the API would be faster (and also avoid creating big files and potentially saturating storage - it happened in the past).
    Any experience on that front ?
    Thanks,

    Etienne

    Hi @Etienne CAUSSE,

    yeah, understood.
    But, whether the API call will be faster in execution compared to the export/reimport is something, I can't answer generally.
    I've only just used the API to call procedures or extracting small (!) layouts, which worked pretty fast.
    And please bear in mind that using the server's memory could easily saturate that as well.
    So, no experience I can come up with to help, sorry.

    Kind regards
    Helmut
