[WIP] feat: Span Streaming POC
This PR contains the POC span streaming implementation for browser SDKs.
Can be tested on @sentry/[email protected] and any higher-level SDKs.
To opt into span streaming, set:
Sentry.init({
dsn: '...',
tracesSampleRate: 1,
traceLifecycle: 'stream', <--
integrations: [
Sentry.browserTracingIntegration();
Sentry.spanStreamingIntegration(); <--
],
// if you use beforeSendSpan, you have to opt into the new serialized span format:
beforeSendSpan: withStreamSpan(serializedSpan => {
// do something
return serializedSpan
}),
})
Also note that spans will no longer be sent to any event processors added via one if the *.addEventProcessor APIs. If you have any event processors, consider using beforeSendSpan or ignoreSpans.
