Update vendor Integrate rendezvous into status node Add a test with failover using rendezvous Use multiple servers in client Use discovery V5 by default and test that node can be started with rendezvous discovet Fix linter Update rendezvous client to one with instrumented stream Address feedback Fix test with updated topic limits Apply several suggestions Change log to debug for request errors because we continue execution Remove web3js after rebase Update rendezvous package

// A NoopTracer is a trivial, minimum overhead implementation of Tracer
|
|
// for which all operations are no-ops.
|
|
//
|
|
// The primary use of this implementation is in libraries, such as RPC
|
|
// frameworks, that make tracing an optional feature controlled by the
|
|
// end user. A no-op implementation allows said libraries to use it
|
|
// as the default Tracer and to write instrumentation that does
|
|
// not need to keep checking if the tracer instance is nil.
|
|
//
|
|
// For the same reason, the NoopTracer is the default "global" tracer
|
|
// (see GlobalTracer and SetGlobalTracer functions).
|
|
//
|
|
// WARNING: NoopTracer does not support baggage propagation.
