v2.41.0

Bigtable

• The Bigtable::DataConnection class has been instrumented to collect Client Side Metrics, free of charge. These metrics will be collected by default if both the OpenTelemetry and Google Cloud Monitoring dependencies are available. Users can opt-out by setting the bigtable::EnableMetricsOption to false.

• The following metrics are available in Bigtable:

  • AttemptLatency
  • OperationLatency
  • RetryCount
  • FirstResponseLatency
  • ServerLatency
  • ApplicationBlockingLatency
  • ConnectivityErrorCount

Spanner

• Multiplexed session support is now available. To enable Multiplexed sessions, add the spanner::EnableMultiplexedSessionOption to Options when calling spanner::MakeConnection. This enables Multiplexed sessions on all operations read-only, read-write, and partitioned.
