Hi,
as far as I can tell there’s no way to configure a separate connection factory to be used for the query side of r2dbc projections. There’s only akka.projection.r2dbc.use-connection-factory which is used for both, the offstore store (read&write) and the projection queries (read only).
Could it make sense to separate those two, so hot standby replicas (which are read only) can be used for the projection queries and hence lower the load on the primary postgres node?
Cheers
Andreas
