Using batch audiences in a journey triggered by streaming audience qualification

Question

Hi there,

Is it possible to use a combination of batch and streaming audiences in a single journey (noting - both use active on edge evaluation method).

I have created a journey with the following:

audience qualification based on a streaming audience using events
Node checks if the member is part of a batch audience
One hour wait
Node checks if member is part of a streaming audience
Email
Five day wait
Node checks if the member is part of a batch audience.

Will this journey reliably work with the combination of streaming and batch audiences?

​@serena_stevensI think it will work structurally, but there's a timing nuance to flag: Node 2 checks batch audience membership immediately after the streaming trigger, before any Wait activity, so it reads from the batch profile projection which can lag up to 2 hours behind actual ingestionmeaning it may not reflect the most current membership right out of the gate.To fix the gap at Node 2-insert a short wait before it.Nodes 4 and 7, however, both occur after a Wait activity, so they actually read from the streaming (unitary) projection (freshness within ~15 minutes) regardless of whether the audience itself is batch or streaming — making them reliable.
