    You don't mention which source type you have in mind. The merge source is technically a black box and cannot be rewound. The merge_datasets and union_datasets sources uses a dot notation in their _updated values. You can edit those manually if you want.


    What is the use-case for rewinding a single source?

    Yeah, this was regarding the merge source. Well, when I do set the "update last seen"-value through dot separation, starting with the first dataset in the datasets poperty of the source, it very often gives me some weird results. I'll try to show an example.

    In this case I'm merging 4 datasets. The datasets property of the source is the following:

    "datasets": ["cvpartner-customer cvc", "currenttime-company cc", "currenttime-company-extra ccx", "ad-customer ad"]

    Starting with cv-partner-customer and ending with ad-customer, their most recent _update-values are:

    629.5105.6044.44407

    If I want to re-send only entities from currenttime-company, from _updated value 5000 I would expect to write 629.5000.6044.44407 in the "update last seen" option.

    This is the result:

     

    In other words, nothing happens after I hit refresh. I often find it hard to correctly do this for merge sources, and quite often I either get no result or the source resend entities I did not specify. That's why I was wondering if there could be a way to specify one dataset individually, instead of marking down all of the, This can also be quite tedious when there are 20 datasets feeding into the source.

    Do you mean "merge_datasets"? The "merge" source does not have _updated values like 629.5105.6044.44407.
