Changelog

0.6.3

  • Delay sending response headers until the first message is ready.
  • Add configurable backpressure to streaming clients.

0.6.1

  • Only buffer stream if queue size is positive (#578, #580)

0.6.0

What changed?

  • Backpressure queue size is controlled by either ZIO_GRPC_BACKPRESSURE_QUEUE_SIZE environment variable or zio_grpc.backpressure_queue_size system property (previously the names were hyphenated). Change was made for compatibility with ZIO Config.
  • GeneratedServices no longer have a R type parameter for generated services. This simplifies the previous APIs and encourages the ZIO 2 style that service dependencies are passed via constructors (see service pattern)
  • Added E type parameter that represents the error type.
  • Context is now received as a second parameter for each handler. For convenience, there is a trait that only takes one parameter (the request type).
  • Introduce Transform for effectful transformations for services that do not have context.
  • Introduce GTransform for effectful transformations over both context and error type.
  • ZTransform[ContextIn, ContextOut] is now a type alias to GTransform that fixes the error channel to StatusException.
  • Classes and methods with suffix ClientWithMetadata have been renamed to ClientWithResponseMetadata.
  • Removed the R type parameter in most APIs.
  • ManagedServer renamed to ScopedServer.
  • Clean shutdown when a server is ran through a Scope or ZLayer.
  • Added backpressure support docs
  • Added client support for response metadata (#428)
  • Signifcant server performance improvement (2.4x faster handling) (#457)
  • Server can now send response metadata (#418)
  • Clients can now access the response metadata sent by server (#428)
  • ServiceList now has a provideLayer and provide that can be used to satisfy services dependencies.
