Coldstart Processor

Status
Stability	in development
Supported pipeline types	traces
Distributions	extension

This processor associates cold start information generated by the telemetryapireceiver with incoming span data processed by the Collector extension. It reads the following of incoming Lambda execution spans identified by the faas.execution attribute:

• trace ID
• parent span ID
• span scope
• resource attributes

This information is stored until the first coldstart span identified by the faas.coldstart attribute is received. That span's trace ID, parent span ID are updated to match the execution span. This allows the coldstart span to be part of the same trace as the operation that triggered the cold start. Additionally, the span scope and resource attributes of the span scope containing the coldstart span are replaced with the span scope and resource attributes of the execution span as they contain more details.

There are currently no configuration parameters available for this processor. It can be enabled via the following configuration:

Package coldstartprocessor correlates cold start information generated by the telemetryapireceiver with incoming span data.

• trace ID
• parent span ID

This information is stored until the first coldstart span identified by the faas.coldstart attribute is received. That span's trace ID, parent span ID are updated to match the execution span. This allows the coldstart span to be part of the same trace as the operation that triggered the cold start. Additionally, the span scope and resource attributes of the span scope containing the coldstart span are replaced with the span scope and resource attributes of the execution span as they contain more details.
