Simple test

import sentry_sdk
from time import sleep

sentry_sdk.init(
    debug=True,
    traces_sample_rate=1.0,
    _experiments={"otel_powered_performance": True},
)

with sentry_sdk.start_span(description="sentry request"):
    sleep(0.1)
    with sentry_sdk.start_span(description="sentry db"):
        sleep(0.5)
        with sentry_sdk.start_span(description="sentry redis"):
            sleep(0.2)
    with sentry_sdk.start_span(description="sentry http"):
        sleep(1)

Misc

In OTel, this:

with tracer.start_as_current_span("parent") as parent:
    with tracer.start_span("child1"):
        pass
    with tracer.start_span("child2"):
        pass

is equivalent to

from opentelemetry import trace, context

parent = tracer.start_span("parent")

# Creates a Context object with parent set as current span
ctx = trace.set_span_in_context(parent)

# Set as the implicit current context
token = context.attach(ctx)

# Child will automatically be a child of parent
child1 = tracer.start_span("child1")
child1.end()

# Child will automatically be a child of parent
child2 = tracer.start_span("child2")
child2.end()

# Don't forget to detach or parent will remain the parent above this call stack
context.detach(token)
parent.end()
