Trace chain element
The purpose of trace.trace{Client, Server} is to
log requests and responses of wrapped NetworkService{Client, Server} to span.
It creates a new span for every Request() or Close().
Instead of logging full request, trace element saves it in context, so that the trace element that wrapped the next client or server, compares the request in the context with its own, and if they do not match, calculates the diff and logs only it. The same with response.
Benchmarks
If we assume that
- logRequest() - logs full
proto.Message - logRequestIfDiffers() - Compares previous and current
proto.Message. Logs the current message only if they differ. - logRequestDiff() - Compares previous and current
proto.Message. If they differ calculates the diff of them and logs only it.
then we get the following results:
| Type | Ops | ns/op |
|---|---|---|
| logRequest() | 32778 | 36565 |
| logRequestIfDiffers() | 33396 | 41140 |
| logRequestDiff() | 34741 | 42793 |
