There was a problem hiding this comment.
Just a small nit on a comment but otherwise LGTM.
…gent is present Adds DATADOG_MINI_AGENT_PATH constant (/tmp/datadog/mini_agent_ready) to detect Lambda Lite + mini agent environments. In that setup: - flushInterval is left at its default (batching is safe; flushInterval=0 would saturate the 8-request exporter limit) - The agent exporter is selected instead of the log exporter, same as when the Datadog Lambda Extension is present

What does this PR do?
Introduces DATADOG_MINI_AGENT_PATH (/tmp/datadog/mini_agent_ready) as a sentinel constant to detect Lambda Lite + mini agent environments, and adjusts two behaviours when that path is present:
This change depends on this serverless-components PR
Motivation
Lambda Lite runs the tracer in a persistent server process alongside a mini agent, rather than the ephemeral invocation model of standard Lambda. The existing Lambda fast-path assumptions (flushInterval = 0, log exporter fallback) are counter-productive in this model and need to be gated on the absence of the mini agent ready file.
