The ESR integration consists mostly from a modern eventful tech stack.
It is composed of the following:
Java 11
Spring boot 2.2
Gradle
TestContainers
RabbitMQ
MongoDB
AWS (Lamda & S3)
Jenkins CICD
Containers for building
The following is a description of each part of the ESR integration
Reconciliation
Services involved:
InboundDataReader
Reconciliation
TCS
This part of the system retrieves a rest request from AWS upon a file upload to the FTP server (S3). The InboundDataRead receives this request and downloads the newly upload file.
Once downloaded, the file is then split into POR/POS/ASG records and each of those types are then sent to the esr.queue.<TYPE>.split queues.
The reconciliation service then picks up the POR/POS types, saves them to the database and sends it to another queue esr.queue.<TYPE>.saved
The same service then picks up the message and tries to find the relating post in TCS by making a rest request. If it exists, the post id is then saved along side the position and a new message is placed on the esr.queue.position.reconciled queue for the AppRecord and Notification services to pick up and process
