Datastore V3 MajorVersion upgrade:

  • Introduction of client side metrics
  • Removal of @deprecated methods and classes and bumping of existing @ObsoleteApi to @deprecated
  • Swapping the default transport from HttpJson to gRPC
  • Configuring a larger default initial channel count and increasing the channel resize_delta to better handle spikes in requests
