dotnet/orleans v1.3.0-beta2

on GitHub

NB: There is a subtle breaking change in this release, which is unfortunately easy to miss.
If you are using AzureSilo.Start(ClusterConfiguration config, string deploymentId) in your code, that overload has been removed, but the new one that replaced it has the same argument signature with a different second argument: (ClusterConfiguration config, string connectionString). Deployment ID now has to be passed as part of the config argument: config.Globals.DeploymentId. This removed the ambiguous possibility of passing two different Deployment IDs, but unfortunately at the cost of the breaking API change.

• Notable new features
  • Support for geo-distributed multi-cluster deployments #1108 #1109 #1800
  • Added new Amazon AWS basic Orleans providers #2006
  • Support distributed cancellation tokens in grain methods #1599
• Providers
  • Remove confusing parameter from AzureSilo.Start #2109
  • Minimal Service Fabric integration #2120
  • Update blob storage provider to throw on storage exceptions #1902
  • Decode protobuf using MessageParser, not dynamic #2136
  • Service Provider is no longer required by EventHubAdapter #2044
  • Preliminary relational persistence queries #1682
  • Add a function that checks the connection string for use during initialization #1987
  • A new ADO.NET storage provider that is significantly easier to setup, which replaces the the previous one. This change is not backwards compatible and does not support sharding
    (likely be replaced later with Orleans sharding provider). The most straightforward migration plan is likely to persist the state classes from Orleans application code.
    More information in #1682 and in #1682 (comment).

• Test
  • Allow liveness config in TestCluster #1818
  • Fix for strange bug in BondSerializer #1790
  • Some improvements for unit testing #1792 #1802
• Other
  • Move JSON serialization methods into OrleansJsonSerializer #2206
  • Updated package dependencies for Azure Storage, ServiceBus, ZooKeeperNetEx, Protobuf and codegen related
  • Remove UseStandardSerializer and UseJsonFallbackSerializer options #2193 #2204
  • Make IGrainFactory injectable #2192
  • Recover types from ReflectionTypeLoadException #2164
  • Moved Orleans Performance Counters into its own Telemetry Consumer. Now you need to explicitly register the OrleansPerfCounterTelemetryConsumer either by code or XML. More information in #2122 and docs will come later. Microsoft.Orleans.CounterControl can still be used to install the performance counters or you can use InstallUtil.exe OrleansTelemetryConsumers.Counters.dll to install it without depending on OrleansCounterControl.exe
