This will have a significant impact on lowering latencies. All of the changes are internal to the client and the existing public surface remains the same. By default the new protocol is disabled and will be slowly enabled in the future using the client config api.

Bigtable clientside metrics are implemented using Opentelemetry. However unlike most libraries + * that use Opentelemetry, the Bigtable client bundles its own exporter that is on by default. The + * metrics collected are exported to Cloud Monitoring. + * + *

There are 3 types of metrics that are collected: + * + *

    + *
  • Table based metrics - these metrics are meant to be the clientside counterpart of the + * serverside bigtable_table metrics. The are tied to Table-bound RPCs. + *
  • Client based metrics - these metrics are internal and used to monitor the e2e health of the + * client. They are tied to the bigtable_client resource. + *
  • Client based gRPC metrics - these are metrics collected by the underlying gRPC library and + * are exported using the bigtable_client resource + *
+ * + *

The client will attach relevant attributes to the measurement when it is being recorded. There + * are 2 types of attributes: resource and metric. Some of the table based resource attributes are + * dynamic and are extracted from an RPC response. To facilitate this, the resource attributes will + * be sent into Opentelemetry as metric attributes and then during export, the attributes will be + * split between the monitored resource and metric labels. + * + *

Client based metrics use a schema that's mostly static, however some of the attributes are + * slow to resolve. The resolution of those attributes will be deferred until the export phase in + * the Exporter. While the non-expensive ones will be sent as metric attributes same as table based + * metrics + * + *

Client based gRPC metrics are recorded by gRPC and don't have access to the any Bigtable + * attributes. All of the Bigtable attributes will be filled in by the Exporter. + * + *

To make this manageable, attributes from different sources are encapsulated by POJOs and are + * plumbed to the RpcTracer and the Exporter. The metrics themselves are wrapped in typesafe + * classes. Each metric has its own class which will have a metric specific record method. In + * addition the metric classes will extend a schema specific class (ie AbstractClientMetric). The + * schema specific class will serve 2 use cases: + * + *

    + *
  • During the record phase, createResourceAttrs method, will ensure all of the resource + * attributes are captured as metric attributes. + *
  • During the export phase, createMonitoredResource and createMetricLabels methods are used to + * extract a MonitoredResource and Metric labels. + *
