    FAQ

    Asked on almost every call.

    How often does the CouchDB Snap Custom Audience sync run?

    Delivery tracks CouchDB, run by application teams running CouchDB: a near-real-time or scheduled sync of your CouchDB documents feeds Snapchat on that cadence. Each run reads only the records changed since the last run, so audiences that rebuild as the segment does holds up on list sizing on Snapchat. The live debugger confirms every delivery inline.

    What match rate should a CouchDB-sourced Snap Custom Audience batch expect?

    Coverage of hashed identifiers across your CouchDB documents decides it, and application teams running CouchDB own that inside CouchDB. A live email or phone matches into Snapchat; neither, and it will not. First-run feedback flags list sizing on Snapchat, which application teams running CouchDB then raise inside your CouchDB documents.
