Does R2dbc support instant updates if some proces inserts, updates, deletes data directly from SQL databases? Or does it only support publishing of such events when data modification actions are done via R2dbc? When I tried running queries and expose as WebFlux stream the stream was completed after successfully streaming all query rrsults Is there a cold / hot Flux that will get either whole result set streamed on new subscription or only modified row(s) for existing / new subscriptions ?
