MiulerHow can we encourage more the use of lagom? any opensource tool built with lagom?
I have 3 micro services for my project
1) Consume External API services using Kafka consumer (service#3)
2) Produce Kafka topic and save into Cassandra db (service#2)
3) API to hit service#2 and which can extended to our external clients (service#1)
kafka_nativeerrors out the box. Any comprehensive guidance on migration will be greatly appreciated.
eventStreammethod in the
persistentEntityRegistry. That produces a
Sourceof all the events, though, at most you can filter by tag, but you can’t filter by persistent ID. Also, note that each client of an
eventStreamcreates one or many polling instances on your database so it is not good to invoke
eventStreamin a unbounded fashion. Use sparingly.
Sharding can be done in two ways, either manually by returning different tags based on information in the event, or automatically by returning a AggregateEventShards tag, which will tell Lagom to shard the tag used based on the entity’s persistence ID. It’s important to ensure all the events for the same entity end up with the same tag (and hence in the same shard), otherwise, event processing for that entity may be out of order, since the read side nodes will consume the event streams for their tags at different paces.
hi, i am looking for some advice, i am building a schema denormaliser. normalized data in mysql and denormalized will be in a NoSQL server
based on my experience i know with the following approach i will be likely to achieve the outcome
i feel this maybe a common problem that already have other solutions, can anyone give some advice? like do i need kafka-streams? do i need the schema-registry?
By default the Service Gateway binds to
localhost. It is possible to change that address by adding this to your build.
lagomServiceGatewayAddress in ThisBuild := "0.0.0.0"
