Overview
We are currently using the Participant Report API to store information about Participants that are not time-series data. Since the data doesn’t have a date associated with it, we are using the dummy date of 2000-12-31. For example, Demographics and Engagement \survey results in mPower 2.0 are stored this way.
Scenarios
Passing Information to the Workers. mPower 2.0 uses the Engagement report to configure SMS notifications.
Save Participant State Outside of the App. The app saves the participant’s responses to Demographics, Engagement, Background, Tasks, etc. This can be used to, for example, drive UI changes or show the participant’s previous responses. Storing this information on the server means it persists when the participant reinstalls the app or changes phones.

DynamoDB
We want to create a new class called DynamoParticipantConfig with the following attributes:
userId (hash key, string)
configId (range key, string)
data (string)
version (Long)
See for example https://github.com/Sage-Bionetworks/BridgeServer2/blob/develop/src/main/java/org/sagebionetworks/bridge/dynamodb/DynamoReportDataDao.java and https://github.com/Sage-Bionetworks/BridgeServer2/blob/develop/src/main/java/org/sagebionetworks/bridge/dynamodb/DynamoReportData.java
Open Questions
Do we want to add study IDs to participant configs and create an index, similar to Report Index?
