What is Apache
Kafka
● Distributed Streaming Platform.
● Client library for building applications
and microservices and unbounded
data.
● Interact with the clusters to process a
stream of data.
● Data is represented in it is as key-value
records

15. Stream Processing in Kafka
Kafka Streams is a library
for building streaming
applications
Streams API
Applications that retrieve
data from Kafka servers
inside which Kafka
producers publish real-time
messages.
Consumer API
Offers an interactive SQL
like interface for
streaming processing.
KSQL

16. Streams Core Concept

17. LEARN NOW
c
Kafka
Streams
● Kafka Streams is a library for building
streaming applications.
● Input Data must be streamed into Kakfa
Topic.
● Parallel Processing, Scalability and Fault
tolerance etc.
● No Cluster needed i.e. Deploy anywhere.

18. LEARN NOW
c
Degree of
Kafka Streams
● Interoperable with streams and tables.
● Fault-tolerant, scalable and efficient
local states.
● Unit Testing Tool.
● Deploy in Containers and manage using
Kubernetes.
● Grouping and Continuously updating
aggregates.
● Flexible windowing capability.
