In a multi-tenant application, for a given domain, is it preferable to use a single journal for a given bounded context or is it preferable to split out the journals per registered institution. An argument can be made that storing it all in one journal is what makes it multi-tenant but an argument can also be made that if you service multiple journals in a single vm that it is still a multi-tenant application. I'm looking for experiences with event sourced multi-tenant applications and the approach others have taken. If using a single journal, there exists a possibility that a given registered institution may consume a larger share of resources than others for example if the journal is being flooded by events from a single institution then the throughput of other institutions will be affected. There are ways to mitigate this but I'd like to get some input from others that have built multi-tenant event sourced applications and the approaches they have taken. Given this, the questions I am asking are as follows:
Is it better to use one journal for this scenario or split it out? If the preferred method is to use a single journal, does it perform well if that journal had multiple event readers (one per institution)reading from it assuming that AKKA persistence and persistence query are being used. Is it better to have one reader of the journal who's sole responsibility is to queue up work in separate queues on something like RabbitMQ and have separate processes that service a single institution read of off its respective queue? -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
