### DD_TRACE_MANAGED_SERVICES (experimental)

Inferred Spans are spans that Datadog can create based on incoming event metadata.
Set `DD_TRACE_MANAGED_SERVICES` to `true` to infer spans based on Lambda events.
Inferring upstream spans is only supported if you are using the [Datadog Lambda Extension](https://docs.datadoghq.com/serverless/libraries_integrations/extension/).
Defaults to `true`.
Infers spans for:

- API Gateway REST events
- API Gateway WebSocket events
- HTTP API events
- SQS
- SNS (SNS messaged delivered via SQS are also supported)
- Kinesis Streams (if data is a JSON string or base64 encoded JSON string)
- EventBridge (custom events, where Details is a JSON string)
- S3
- DynamoDB
