[dwijnand]

• @dwijnand Play + Akka v2.6.0-M8 (ActorContext DI change) play#9712 play#9715
• @marcospereira Solve dependency injection for typed Scheduler
  • Figure it out if it needs to be a singleton or not
• @dwijnand Play: Release v2.8.0-M6 (w/ Akka v2.6.0-M8)
• @ignasi35 Lagom: Release notes for v1.6.0-M6
• @renatocaval Lagom: add a tagging adapter for Akka Persistence Typed tagging lagom#2312
• @dwijnand Lagom: Release v1.6.0-M7 (w/ Akka v2.6.0-M8 & Play v2.8.0-M6) - Upgrade to Akka 2.6.0-M8 & Play 2.8.0-M6 lagom/lagom#2350
• Lagom: document uses of Akka Persistence Typed
  • @renatocaval How to do persistence using Akka Persistence Typed in Lagom applications
    • Scala users need to learn how to use Akka Jackson for the commands (ActorRef[Reply] issue)
  • @renatocaval How to migrate from classic Lagom persistence API to Akka Persistence Typed
    • Java users need to learn how to remove PersistenceId separator
  • @ignasi35 Adapt our sbt seeds to use Akka Persistence Typed (1.6.x branches)
  • @ignasi35 Adapt our maven archetype to use Akka Persistence Typed
• Adapt lagom-samples to use Akka Persistence Typed (1.6.x branch) - blocked, awaiting 1.6.0-M7
  • @renatocaval shopping-cart
  • @marcospereira mixed-persistence

Metadata

• Dates: 2019-10-07 - 2019-10-18
• Previous Sprint
• Support Rota: Ignasi then Marcos
• Person days: 24/30
  • Renato out 3
  • Dale out 2
  • Marcos out 1

Scope for next sprint

• Play: add a sample (to play-samples) using Akka Persistence Typed + advertise in 2.8 highlights
  • Cluster sharding
  • Cluster formation
• Jackson 2.10 after Akka 2.6.0-RC1

Backlog

• lagom and play samples
  • lagom gRPC samples issues
    • lagom-grpc-scala not using latest milestone
    • latest proto-to-java generators use deprecated API (both Akka-grpc and protoc itself)
    • miss-alignemt on Akka-HTTP versions (Play and Lagom use 10.1.0, akka-grpc uses 10.1.9). Causes runtime errors. Requires users to add dependencyOverrides
• akka-discovery-service-loc is DNS_SVR eager (akka-discovery-service-locator eagerly uses DNS-SRV Lookups lagom/lagom#2299)
• ServiceClientModule breaking Lagom mocking tests Play tests with mocked Lagom services fails to build Injector lagom/lagom#2307

Other things discussed last week.

Requires attention next sprint

• @ignasi35 release milestones with Akka 2.6.0-M8
• Jackson 2.10
  • @marcospereira play-json we can already update it
• Finish the work around Play-CQRS
  • Tagging adapter
  • Reference docs
  • Sample application
• lagom and play samples
  • lagom gRPC samples issues
    • lagom-grpc-scala not using latest milestone
    • latest proto-to-java generators use deprecated API (both Akka-grpc and protoc itself)
    • miss-alignemt on Akka-HTTP versions (Play and Lagom use 10.1.0, akka-grpc uses 10.1.9). Causes runtime errors. Requires users to add dependencyOverrides

These aren't high priority

• akka-discovery-service-loc is DNS_SVR eager (akka-discovery-service-locator eagerly uses DNS-SRV Lookups lagom/lagom#2299)
• ServiceClientModule breaking Lagom mocking tests Play tests with mocked Lagom services fails to build Injector lagom/lagom#2307
