Basic Features

  • Hertz
    • Use thrift IDL to define HTTP interface
    • Use hz to generate server/client code
    • Use Hertz binding and validate
    • Use obs-opentelemetry and jarger for tracing, metrics, logging
    • Middleware
      • Use requestid, jwt, recovery, pprof, gzip
  • Kitex
    • Use thrift IDL to define RPC interface
    • Use kitex to generate code
    • Use thrift-gen-validator for validating RPC request
    • Use obs-opentelemetry and jarger for tracing, metrics, logging
    • Use registry-etcd for service discovery and register
