Reference documentation and code samples for the Cloud Bigtable V2 Client class RequestLatencyStats.
RequestLatencyStats provides a measurement of the latency of the request as it interacts with different systems over its lifetime, e.g. how long the request took to execute within a frontend server.

Google\Protobuf\Duration
The latency measured by the frontend server handling this request, from when the request was received, to when this value is sent back in the response. For more context on the component that is measuring this latency, see: https://cloud.google.com/bigtable/docs/overview Note: This value may be slightly shorter than the value reported into aggregate latency metrics in Monitoring for this request (https://cloud.google.com/bigtable/docs/monitoring-instance) as this value needs to be sent in the response before the latency measurement including that transmission is finalized. Note: This value includes the end-to-end latency of contacting nodes in the targeted cluster, e.g. measuring from when the first byte arrives at the frontend server, to when this value is sent back as the last value in the response, including any latency incurred by contacting nodes, waiting for results from nodes, and finally sending results from nodes back to the caller. |
