    Multiple Data/Metadata Adapters

    Hi,

    I'm currently evaluating LS 3.5 new features and could not find any sample of multiple data adapters / metadata adapters in .NET.

    Does LS 3.5 supports this feature with web client API and .NET adapters server side ? (ie. with a single connection subscribing to multiple metadata/data adapters pairs or to a single metadata adapter with multiple data adapters).

    Hi Olivier,

    each client session is bound to a single adapter set that is composed of a single metadata adapter and any number of data adapters.

    you can configure your adapter set with any kind of data adapters, so that you can use multiple .NET data adapters in a single adapter set.

    Note that there is no way to connect to two metadata adapters within a single session.

    Let me know if you have any doubts.

    Bye.

    Hi Mone,

    Thanks for your answer,

    I'm curious about this design decision : why did the LS team choose the single metadata adapter / multiple data adapters instead of working with multiple metadata/data adapters pairs ? Enabling client API to bind each pushtable to different data/metadata adapter pair.

    Bye,

    Olivier

    Hi Olivier,

    Because the Metadata Adapter manages some aspects that pertain to the overall user's session (such as authentication, stream bandwidth, etc.), so that having multiple Metadata Adapters as part of the same session would not be possible.

    Just curious to see any example with single metadata adapter having multiple data adapters with multiple schema set. It would be great to see such reference or example. thanks

    Hi mhasan,

    please refer to the "Full Version of the Portfolio Demo", as an example that shows how to integrate two Adapters in the same Adapter Set.

    Regards,

    Hi mhasan,

    Here you can find the .NET version of the Portfolio Demo, which shows the same integration mentioned in the previous post.
