Hi Gopinath Panneerselvam,
The ICAI connector guide is here: https://network.informatica.com/onlinehelp/IICS/prod/CAI/en/index.htm#page/aa-cai-connectors/Preface.html
At a high level:
1. Create an Amazon S3 connection, File Connection, JDBC connector to AWS Document DB and create Amazon SNS connection.
2. Create a process to listen to Amazon S3 connection and download the file into the local system where the secure agent can be installed.
3. Create a process that consumes this JSON file and parses into Process object list and inserts into Document DB.
4. One of the steps in the process(Step 3) would be to push a message into the Amazon SNS topic once it has created the record successfully.
