A Splitter is useful to break out a single message into a sequence of sub-messages that can be processed individually. Likewise, a Recipient List or a Publish-Subscribe Channel is useful to forward a request message to multiple recipients in parallel in order to get multiple responses to choose from. In most of these scenarios, the further processing depends on successful processing of the sub-messages. For example, we want to select the best bid from a number of vendor responses or we want to bill the client for an order after all items have been pulled from the warehouse.
The Aggregator is a special Filter that receives a stream of messages and identifies messages that are correlated. Once a complete set of messages has been received (more on how to decide when a set is 'complete' below), the Aggregator collects information from each correlated message and publishes a single, aggregated message to the output channel for further processing.
There are a number of strategies for aggregator completeness conditions. The available strategies primarily depend on whether we know how many messages to expect or not. The Aggregator could know the number of sub-messages to expect because it received a copy of the original composite message or because each individual message contains the total count (as described in the Splitter example). Depending on how much the Aggregator knows about the message stream, the most common strategies are as follows:
The modern implementation of the Loan Broker using AWS serverless constructs includes an implementation of a Aggregator with Lambda and DynamoDB. The Aggregator uses a simple completeness condition of waiting for a minimum number of answers. The surrounding workflow, implemented using AWS Step Functions, adds a time-out component.
The modern implementation of the Loan Broker using GCP includes an implementation of a Aggregator with a Cloud Function and Datastore. The implementation stores all elements of a specific Aggregate under the same key and can therefore fail when inserting the record (Datastore doesn't seem to like heavy contention on one record). It therefore configures retry logic on the incoming messages. The Aggregator signals back to the Process Manager on completion.

Did you connect the output of the learner node to the x-aggregator? That would explain duplicate row IDs because the learning sets overlap. The typical use case is that you connect the output of the predictor to the aggregation node.
Earning the Data Aggregator Validation designation conveys to health plans, providers, government organizations and others that they can trust the accuracy of aggregated clinical data for use in Healthcare Effectiveness Data and Information Set (HEDIS) reporting and other quality programs. NCQA is trusted industry-wide for setting standards and creating programs that improve health care quality.
Data from health information exchanges (HIEs) and other data aggregators are increasingly used as supplemental data for HEDIS reporting. Data from data streams validated by NCQA can be used as standard supplemental data in HEDIS reporting, eliminating the need for primary source verification (PSV) during the HEDIS audit process.
Any data stream that meets the standards of the program can be validated by NCQA. The validated status is conferred to the data stream. Organizations that are responsible for certain standards as part of the validation will earn a Certified Data Partner status for Data Aggregator Validation and can advertise themselves as supporting the NCQA Data Aggregator Validation program. There are two statuses that successful participates can achieve.
Organizations that perform all functions in the program requirements, including facilitating primary source verification, can act as the sole responsible party for meeting validating a data stream by meeting all program standards.
The aggregation of data sometimes involves multiple parties. For example, an organization might be responsible for the management of the data and output of the CCD or FHIR file, but not have legal access to the primary source data to support PSV. In these cases, the organization that can facilitate PSV is the responsible party for the data stream, but they can partner with other organizations to validate a data stream.
The first step to validating a data stream is a discussion with an NCQA program expert. Purchase and review the program resources and conduct a gap analysis against the program requirements to ensure you will meet the program requirements. Once ready, submit your online application.
The Data Aggregator Validation customer completes an inventory of the ingestion sites they would like to get validated on the Data Submission Log (DSL). The validator reviews the inventory list and groups ingestion sites into clusters based on like care setting + EHR type.
NCQA assesses the conformance of the outbound CCD or FHIR data to the specified HL7 CCD or FHIR Implementation Guide. The primary source verification process involves ensuring that the data in the conformed output CCD or FHIR resources matches the primary source data found in the source EHR.
Continuity of Care Documentation (CCD) and Fast Healthcare Interoperability Resources (FHIR) are both healthcare industry standards for exchanging patient health information, with CCD being the more established.
Several key policies and initiatives, including the 21st Century Cures Act, the ONC Cures Act Final Rule, and the CMS Interoperability and Patient Access Rule, actively endorse and promote the further adoption of FHIR as the standard of choice for healthcare data exchange.
NCQA works with organizations to ensure their data output adheres to the HL7 C-CDA R2.1 Implementation Guide in the June 2020 errata package, available on the HL7 C-CDA product page, or in the US Core Implementation Guide STU3 (v3.1.1 R4) available in the HL7 FHIR Implementation Guide Registry.
When i create the aggregator in the root account is was returning an error that it couldn't connect to accounts using the default IAM so i let it create one which i can see in the root org has: AWSConfigRoleForOrganizations policy attached. This creates the aggregator But no accounts are listed from it and no results are shown from it.
So after a 3 days suddenly everything is populated! we only have 5 accounts so really wasnt expecting it to take that long! but it is now fully working.. So good note to wait a week if you aggregator builds and doesnt generate errors!
Another useful check would be to determine if your organization is being governed by Control Tower. If this is the case; instead of using AWSConfigRoleForOrganizations, you must use AWSControlTowerConfigAggregatorRoleForOrganizations role.
