Would it be possible to support opentracing inject/extract API for this case? Which could look like:
from thundra.thundra_agent import Thundra
thundra = Thundra()
@thundra
def handler(event, context):
tracer = ThundraTracer.get_instance()
result = {'message': 'hello'}
tracer.inject(
tracer.scope_manager.active(), // <- not sure of the API call to get the active span
opentracing.Format.TEXT_MAP,
result,
)
return result
Then the invoked lambda, either explicitly calls extract
or the thundra tracer agent inspects the payload?
from thundra.thundra_agent import Thundra
thundra = Thundra()
@thundra
def handler(event, context):
tracer = ThundraTracer.get_instance()
span_context = tracer.extract(
format=opentracing.Format.TEXT_MAP,
carrier=context,
)
with tracer.start_active_span(operation_name="write_user_to_db", childOf=span_context) as scope:
# perform operation
print('received: {} {}'.format(event, context))
return {'hi': 'hi'}

Hello, add_outgoing_trace_link
and add_incoming_trace_link
functions can be used to connect the async lambda, you can use an identifier for the trace as a trace link and add it into your response and use it in the invoked lambda. (To use this functions as below, thundra agent version should be >= 2.5.10 and layer >=48)
Lambda 1
import uuid
import thundra
def lambda_handler(event, context):
# use any trace identifier here
trace_link = str(uuid.uuid4())
thundra.add_outgoing_trace_link(trace_link)
return {
'message': 'hello',
'thundra_trace_link': trace_link
}
Lambda 2
import thundra
def lambda_handler(event, context):
thundra_trace_link = event.get("responsePayload", {}).get("thundra_trace_link")
if thundra_trace_link is not None:
thundra.add_incoming_trace_link(thundra_trace_link)
