v1.74.2: Release 1.74.2

Compare Source

API Changes

• balancer: add ExitIdle method to Balancer interface. Earlier, implementing this method was optional. (#​8367)

Behavior Changes

• xds: Remove the GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST environment variable that allows disabling the least request balancer with xDS. Least request was made available by default with xDS in v1.72.0. (#​8248)
  • Special Thanks: @​atollena
• server: allow 0s grpc-timeout header values, which older gRPC-Java versions could send. This restores the behavior of grpc-go before v1.73.0. (#​8439)

Bug Fixes

• googledirectpath: avoid logging the error message Attempt to set a bootstrap configuration... when creating multiple directpath channels. (#​8419)

Performance Improvements

• transport: reduce heap allocations by pooling objects and avoiding method-to-closure conversions. (#​8361)
• transport: reduce heap allocations by re-using mem.Reader objects. (#​8360)

Documentation

• examples: add examples to demonstrate enabling experimental metrics using the OpenTelemetry plugin. (#​8388)
  • Special Thanks: @​vinothkumarr227
