It connects to its own peers. + + * comes with a cache filling mechanism. Whereas memcached just says + "Sorry, cache miss", often resulting in a thundering herd of + database (or whatever) loads from an unbounded number of clients + (which has resulted in several fun outages), groupcache coordinates + cache fills such that only one load in one process of an entire + replicated set of processes populates the cache, then multiplexes + the loaded value to all callers. + + * does not support versioned values. If key "foo" is value "bar", + key "foo" must always be "bar". There are neither cache expiration + times, nor explicit cache evictions. Thus there is also no CAS, + nor Increment/Decrement. This also means that groupcache.... + + * ... supports automatic mirroring of super-hot items to multiple + processes. This prevents memcached hot spotting where a machine's + CPU and/or NIC are overloaded by very popular keys/values. + + * is currently only available for Go. It's very unlikely that I + (bradfitz@) will port the code to any other language. + +## Loading process + +In a nutshell, a groupcache lookup of **Get("foo")** looks like: + +(On machine #5 of a set of N machines running the same code) + + 1.

If so, use it. + + 3. Amongst all the peers in my set of N, am I the owner of the key + "foo"? (e.g. does it consistent hash to 5?) If so, load it. If + other callers come in, via the same process or via RPC requests + from peers, they block waiting for the load to finish and get the + same answer. If not, RPC to the peer that's the owner and get + the answer.

OpenCensus allows +you to instrument your services and collect diagnostics data all +through your services end-to-end. + +## Tags + +Tags represent propagated key-value pairs. They are propagated using `context.Context` +in the same process or can be encoded to be transmitted on the wire. Usually, this will +be handled by an integration plugin, e.g. `ocgrpc.ServerHandler` and `ocgrpc.ClientHandler` +for gRPC. + +Package `tag` allows adding or modifying tags in the current context. + +[embedmd]:# (internal/readme/tags.go new) +```go +ctx, err := tag.New(ctx, + tag.Insert(osKey, "macOS-10.12.5"), + tag.Upsert(userIDKey, "cde36753ed"), +) +if err != nil { + log.Fatal(err) +} +``` + +## Stats + +OpenCensus is a low-overhead framework even if instrumentation is always enabled. +In order to be so, it is optimized to make recording of data points fast +and separate from the data aggregation. + +OpenCensus stats collection happens in two stages: + +* Definition of measures and recording of data points +* Definition of views and aggregation of the recorded data + +### Recording + +Measurements are data points associated with a measure. +Recording implicitly tags the set of Measurements with the tags from the +provided context: + +[embedmd]:# (internal/readme/stats.go record) +```go +stats.Record(ctx, videoSize.M(102478)) +``` + +### Views + +Views are how Measures are aggregated. You can think of them as queries over the +set of recorded data points (measurements). + +Views have two parts: the tags to group by and the aggregation type used. + +Currently three types of aggregations are supported: +* CountAggregation is used to count the number of times a sample was recorded. +* DistributionAggregation is used to provide a histogram of the values of the samples. +* SumAggregation is used to sum up all sample values. + +[embedmd]:# (internal/readme/stats.go aggs) +```go +distAgg := view.Distribution(1<<32, 2<<32, 3<<32) +countAgg := view.Count() +sumAgg := view.Sum() +``` + +Here we create a view with the DistributionAggregation over our measure. + +[embedmd]:# (internal/readme/stats.go view) +```go +if err := view.Register(&view.View{ + Name: "example.com/video_size_distribution", + Description: "distribution of processed video size over time", + Measure: videoSize, + Aggregation: view.Distribution(1<<32, 2<<32, 3<<32), +}); err != nil { + log.Fatalf("Failed to register view: %v", err) +} +``` + +Register begins collecting data for the view. Registered views' data will be +exported via the registered exporters. + +## Traces + +A distributed trace tracks the progression of a single user request as +it is handled by the services and processes that make up an application. +Each step is called a span in the trace. Spans include metadata about the step, +including especially the time spent in the step, called the span’s latency. + +Below you see a trace and several spans underneath it. + +![Traces and spans](https://i.imgur.com/7hZwRVj.png) + +### Spans + +Span is the unit step in a trace. Each span has a name, latency, status and +additional metadata. + +Below we are starting a span for a cache read and ending it +when we are done: + +[embedmd]:# (internal/readme/trace.go startend) +```go +ctx, span := trace.StartSpan(ctx, "cache.Get") +defer span.End() + +// Do work to get from cache. +``` + +### Propagation + +Spans can have parents or can be root spans if they don't have any parents. +The current span is propagated in-process and across the network to allow associating +new child spans with the parent. + +In the same process, `context.Context` is used to propagate spans. +`trace.StartSpan` creates a new span as a root if the current context +doesn't contain a span. Or, it creates a child of the span that is +already in current context. The returned context can be used to keep +propagating the newly created span in the current context. + +[embedmd]:# (internal/readme/trace.go startend) +```go +ctx, span := trace.StartSpan(ctx, "cache.Get") +defer span.End() + +// Do work to get from cache. +``` + +Across the network, OpenCensus provides different propagation +methods for different protocols. + +* gRPC integrations use the OpenCensus' [binary propagation format](https://godoc.org/go.opencensus.io/trace/propagation). +* HTTP integrations use Zipkin's [B3](https://github.com/openzipkin/b3-propagation) + by default but can be configured to use a custom propagation method by setting another + [propagation.HTTPFormat](https://godoc.org/go.opencensus.io/trace/propagation#HTTPFormat). + +## Execution Tracer + +With Go 1.11, OpenCensus Go will support integration with the Go execution tracer. +See [Debugging Latency in Go](https://medium.com/observability/debugging-latency-in-go-1-11-9f97a7910d68) +for an example of their mutual use. + +## Profiles + +OpenCensus tags can be applied as profiler labels +for users who are on Go 1.9 and above. + +[embedmd]:# (internal/readme/tags.go profiler) +```go +ctx, err = tag.New(ctx, + tag.Insert(osKey, "macOS-10.12.5"), + tag.Insert(userIDKey, "fff0989878"), +) +if err != nil { + log.Fatal(err) +} +tag.Do(ctx, func(ctx context.Context) { + // Do work. + // When profiling is on, samples will be + // recorded with the key/values from the tag map. +}) +``` + +A screenshot of the CPU profile from the program above: + +![CPU profile](https://i.imgur.com/jBKjlkw.png) + +## Deprecation Policy + +Before version 1.0.0, the following deprecation policy will be observed: + +No backwards-incompatible changes will be made except for the removal of symbols that have +been marked as *Deprecated* for at least one minor release (e.g. 0.9.0 to 0.10.0).
