A Kafka cluster stores streams of records (messages) in categories called topics. It is the architectural backbone for integrating streaming data with a Data Lake, Microservices and Stream Processing. Today's enterprises have their core systems often implemented on top of relational databases, such as the Oracle RDBMS. Implementing a new solution supporting the digital strategy using Kafka and the ecosystem can not always be done completely separate from the traditional legacy solutions. Often streaming data has to be enriched with state data which is held in an RDBMS of a legacy application. It's important to cache this data in the stream processing solution, so that It can be efficiently joined to the data stream. But how do we make sure that the cache is kept up-to-date, if the source data changes? We can either poll for changes from Kafka using Kafka Connect or let the RDBMS push the data changes to Kafka. But what about writing data back to the legacy application, i.e. an anomaly is detected inside the stream processing solution which should trigger an action inside the legacy application. Using Kafka Connect we can write to a database table or view, which could trigger the action. But this not always the best option. If you have an Oracle RDBMS, there are many other ways to integrate the database with Kafka, such as Advanced Queueing (message broker in the database), CDC through Golden Gate or Debezium, Oracle REST Database Service (ORDS) and more. In this session, we present various blueprints for integrating an Oracle RDBMS with Apache Kafka in both directions and discuss how these blueprints can be implemented using the products mentioned before.

5. Microservices / Modern Applications
• Highly decoupled
• Independently deployable
• Bounded Context/Aggregate (DDD)
• Responsible for their data
• Favour asynchronous, event-driven
interaction over synchronous
• Smart Endpoints and Dump Pipes
• Use Anti-Corruption Layer (ACL) if no
fit! M3M2

• Many connectors available
• Single Message Transforms (SMT)
• declarative style, simple data flows
• framework is part of Apache Kafka

21. Oracle REST Data Services (ORDS)
• makes it easy to develop modern REST interfaces for relational data in the
Oracle Database and the Oracle Database 18c JSON Document Store
• ORDS maps HTTP(S) verbs (GET, POST, PUT, DELETE, etc.) to database
transactions and returns any results formatted using JSON
• Java middle tier application on WebLogic, Tomcat, Docker, Standalone (for
development)

22. DB-K_3 – Setup ORDS (I)

p_items_per_page => 25,
p_source =>
'SELECT ''application/json'', json_object(''orderId'' VALUE po.id,
''orderDate'' VALUE po.order_date,
''orderMode'' VALUE po.order_mode,
''customer'' VALUE
json_object(''firstName'' VALUE cu.first_name,
''lastName'' VALUE cu.last_name
''emailAddress'' VALUE cu.email),
''lineItems'' VALUE (SELECT json_arrayagg(
json_object(''ItemNumber'' VALUE li.id,
''Product'' VALUE
json_object(''id'' VALUE li.product_id,

FROM order_item_t li WHERE po.id = li.order_id),
''offset'' VALUE TO_CHAR(po.modified_at, ''YYYYMMDDHH24MISS''))
FROM order_t po LEFT JOIN customer_t cu ON (po.customer_id = cu.id)
WHERE po.modified_at > TO_DATE(:offset, ''YYYYMMDDHH24MISS'')'

• Both stream and batch
processing
• custom sources, sinks,
