Module trace_utils_v1 

Trace-utils functionalities implementation for V1 spans.

Functions

compute_top_level_span

Updates all the spans top-level attribute. A span is considered top-level if:

drop_chunks

Remove spans and chunks, only keeping the ones that may be sampled by the agent.

get_root_span_index

Returns the index of the root span in trace.

has_top_level

Returns true if the span has a top level key set

is_measured

Returns true if a span should be measured (i.e., it should get trace metrics calculated).

is_partial_snapshot

Returns true if the span is a partial snapshot. This kind of spans are partial images of long-running spans. When incomplete, a partial snapshot has an attribute _dd.partial_version which is a positive integer. This value usually increases each time a new version of the same span is sent by the tracer
