Hi,

One thing to point out here is there were a few timestamp fields that
exist for Split-join enrichment topology that haven't been made to the
unified one. For example, there is no threat intel bolt timestamp. There
might be some SLA related use cases regarding these timestamp fields that
might be nice to have before depreciation of the split-join one. Generally
speaking, makes sense to deprecate split-join topology, though.

Cheers,
Ali
