Jobs (CSE)

UM Cron Jobs can call custom CSE functions. In this example we will implement a function that performs a mass operation to remove all members of a given Segment from a given List.

Create a new file cmsbs-conf/cse/plugins/de.acme.tutorial/custom/removeSegmentFromList.mjs:

de.acme.tutorial.removeSegmentFromList = (segmentName, listName) => {
    const query = UM.query(`inChannel(${listName}) and inVChannel(${segmentName})`);

    while (true) {
        let entries = query.page(100, 0); // 100 per page, stay on page 0!
        if (entries.length == 0) break;
        entries.forEach(entry => {
            entry.channels.unsubscribe(listName);
        });
        UM.commitEntries();
        UM.test.emptyEntryCache();
    }
}
