  • Large number of transactions failed due to insufficient customer credit limits.

  • Customers with good credit history should be given an immediate increase in credit limits.

  • Limitations of the existing data infrastructure not able to compute consumer spending limits and credit limits in real-time, resulting in poor customer experience and customer churn.


  • Synchronize credit card transaction information from the credit card systems
    using CDC (Change Data Capture).

  • Use JDBC source Connector to ingest customer data that is related to credit limits
    into Confluent.

  • Transform CDC data using KStreams to prepare it for subsequent analysis and calculate the customer's monthly spending and determine if it has reached 70% of the limit threshold.

  • The credit limit model determines the new credit limit and writes the data back into Confluent and a consumer application will send notification to customers by SMS


  • The solution enables real-time communication and interaction with events to harness the value of the
    real-time data.

  • With Confluent we can accelerates enterprise innovation to enhances
    customer experiences and therefore reduce customer churn
