DistributionSamples is similar to Distribution, but it lets the client deals with the sampling, rate is passed to the agent and not used for further sampling. WithMaxBufferedMetricsPerContext is ignored when using this method.
Because this is a shift compared to how other methods are behaving, this method is provided only in ClientDirect which provides direct access to some low level dogstatsd protocol features like DataDog/datadog-go#extended-aggregation
This is recommended in high performance cases were the overhead of the statsd library might be significant and the sampling is already done by the client.
NewDirect
andNewDirectWithWriter
can be used to instantiate a new direct client, mocks and noop clients are available.replaces #292
