Kitex Release v0.14.0

Introduction to Key Changes

New Features

1. Generic Call: The generic Client supports streaming calls, allowing a single Client to handle both streaming and non-streaming scenarios

   It supports streaming generic calls, adapting to gRPC/TTHeader Streaming and supporting map/JSON and Protobuf binary generic calls.

   A brief code example is as follows:

   cli, err := genericclient.NewClient("actualServiceName", g)
   // Ping-Pong generic
   resp, err := cli.GenericCall(ctx, "PingPongTest", req)
   // ClientStreaming generic
   cliStream, err := cli.ClientStreaming(ctx, "ClientStreamingTest")
   // ServerStreaming generic
   srvStream, err := cli.ServerStreaming(ctx, "ServerStreamingTest", req)
   // BidiStreaming generic
   bidiStream, err := cli.BidiStreaming(ctx, "BidiStreamingTest")
   

   Refer to this document for details: Generic Call.

Feature/Experience Optimization

1. Streaming: Improved observability and debugging experience

   TTHeader Streaming

   • If Tracer configured, failure to create a stream will now be reported with metrics.
   • When a panic occurs on the Server side, the full stack trace will now be printed for easier troubleshooting.

   gRPC Streaming

   • If Tracer configured, failure to create a stream will now be reported with metrics.

Others

1. Code Product Simplification

   Kitex tool no longer generates fastpb, only affecting Protobuf users.

   If high-performance Protobuf encoding/decoding is required, you can enable prutal by configuring environment variable KITEX_TOOL_USE_PRUTAL_MARSHAL=1.
