I have an AWS instance doing this for me right now. Would love to kill that instance and just use the Datomic Cloud infrastructure going forward. What would you suggest?
is your processing triggered by something external? i.e. something you can hook up to an SNS queue?
The long running process is a Kafka consumer, consuming a few thousand messages a second. I'm not sure it fits in with an external trigger?
Hi, has anyone tried reading datomic data into a spark RDD? I saw the Nubank video/slides and I wonder if that’s still the state of the art.
Hi @stuarthalloway, when can we expect Datomic Cloud will be available in ap-southeast-1?
@1zaak in the next release
how y'all deal with (possibly) nil query parameters? for example, a broken query to collect all public catalogue items and those catalogue items for which a user has particular access
(d/q '{:find [(pull ?catalogue-item [*])]
:in [$ ?person-id]
:where [
[?catalogue-item :view/visibility :public]
(or-join [?catalogue-item ?person-id]
[?person-id :access/owns ?catalogue-item])
]}
db
; could be nil:
<some-person-id>
)
What strategies are people using to effectively SIGHUP all nodes in a query group, say, to restart/reload with a new configuration (but no code change)?
@stuarthalloway What about when Datomic cloud will be available in sa-east-1?
