Steps
Deploy the aws.greengrass.StreamManager component to the core device
Grant the core device's token exchange role permissions for each cloud destination you plan to export to (Kinesis, S3, IoT Analytics, IoT SiteWise)
From a component using the per-language Stream Manager SDK, create a MessageStreamDefinition with a name, max size, and a StrategyOnFull policy (RejectNewData or OverwriteOldestData)
Attach an ExportDefinition to the stream pointing at the target destination
Append data to the local stream via SDK calls; Stream Manager buffers it locally during connectivity loss and exports when possible
Verify successful export via CloudWatch logs or the destination service
Known gotchas
StrategyOnFull only offers reject-new-data or overwrite-oldest-data - plan buffer sizing accordingly
The token exchange role must explicitly permit each export destination or exports fail silently
Some Stream Manager component versions require an incremental upgrade path rather than a direct jump - check release notes before upgrading
