Tech

SB-CB-EXT uses a number of open source projects:

• [APACHE KAFKA] - used for data pipeline and data integration
• [APACHE CASSANDRA] - No sql data base used for scalability and high availability
• [ELASTIC SEARCH] - No sql data base used for great searching capability
• [SPRING BOOT] - Great framework to work with java.
• [JAVA] - used for core development
• [POSTGRESQL] - a relational database

Installation

Kafka Topics Required

• orgCreation - Used to create SB Org object when new Department is created
• userRoleAuditTopic - Used to update the user_department_role record in Audit table
