iFix Core Fiscal Event Post Processor v2.0

Overview

Fiscal Event Post Processor is a streaming pipeline for validated fiscal event data. Apache Kafka has been used to stream the validated fiscal event data, process it for dereference, unbundle, flatten And finally push these details to Druid data store.

Version

Current version : 2.0.0

Prerequisites

Before you proceed with the configuration, make sure the following pre-requisites are met

1. Java 8

2. Apache Kafka and Kafka-Connect server should be up and running

3. Druid DB should be up and running

4. Below dependent services are required:
   iFix Master data service
   iFix Fiscal Event service

Features

Fiscal Event post-processor consumes the fiscal event validated data from Kafka topic named “fiscal-event-request-validated” and process it by following below steps :

1. Fiscal event validated data will get dereferenced. For dereferencing, pass the service ids like COA id, Tenant id etc. to corresponding services - Master service And get the corresponding object(s). Once the fiscal event data is dereferenced, push/send the same data to dereference Topic.

2. Unbundle consumers pick up the dereferenced fiscal event data from dereferencing topic. Dereference fiscal event data gets unbundled and then flattened. Once the flattening is complete, push/send the same data to Druid Sink topic.

3. Flattened fiscal event data is pushed to Druid DB from a topic named: fiscal-event-druid-sink.

Kafka to Data Store Sink

MongoDB Sink

The Kafka-connect is used to push the data from a Kafka topic to MongoDB. Follow the steps below to start the connector:

1. Connect (port-forward) with the Kafka-connect server.

2. Create a new connector with a POST API call to localhost:8083/connectors.

3. The request body for that API call is written in the file fiscal-event-mongodb-sink.

4. Within that file, wherever ${---} replace it with the actual value based on the environment. Get ${mongo-db-authenticated-uri} from the configured secrets of the environment.
   (Optional) Verify and make changes to the topic names.

5. The connector is ready. You can check it using API call GET localhost:8083/connectors.

Druid Sink

The Druid console is used to start ingesting data from a Kafka topic to the Druid data store. Follow the steps mentioned below to start the Druid Supervisor

1. Open the Druid console

2. Go to the Load Data section

3. Select Other

4. Click on Submit Supervisor

5. Copy...Paste the JSON from the druid-ingestion-config.json file in the available text box.

6. Verify the Kafka topic name and the Kafka bootstrap server address before submitting the config

7. Submit the config and the data ingestion should start into the fiscal-event data source
