Stream Processing Topology in Kafka
Kafka Streams is a stream processing platform for building event-driven applications and microservices. It is a distributed stream processing framework that is built on top of Apache Kafka.
The stream processing topology in Kafka Streams comprises three components: a source processor, a sink processor, and an intermediate processor.
A source processor is responsible for ingesting data from an external source, such as a database or a message queue system. It can also transform the data into a format that is compatible with Kafka Streams.
The sink processor is responsible for writing the data to an external sink, such as a database or a message queue system. Finally, the intermediate processor is responsible for performing data transformations and aggregations.
A) Sink Processor
The sink processor is responsible for writing the data to an external sink. It can be used to write the data to a database, a message queue system, or a file system. The sink processor is typically used to write the data to a sink that is not compatible with Kafka Streams.
B) Source Processor
The source processor is responsible for ingesting data from an external source. It can be used to read data from a database, a message queue system, or a file system. The source processor is typically used to read data from a source incompatible with Kafka Streams.
Kafka Streams Architecture
Kafka Streams is built on top of Apache Kafka and is designed to provide a distributed stream processing platform. The Kafka Streams architecture consists of a stream processing topology composed of a source processor, a sink processor, and an intermediate processor.
It also includes a threading model, local state stores, and fault-tolerance features.
The Kafka Streams architecture is designed to be highly scalable and supports horizontal scaling by increasing the number of nodes. It also supports vertical scaling by allowing the resources of each node to be increased.
1. Streams Partitions and Tasks
In Kafka Streams, data is processed in parallel across different partitions. Each partition is assigned a task responsible for processing the data for that partition. The number of tasks is equal to the number of partitions, and the number of partitions can be increased to increase the parallelism of the stream processing.
The tasks are assigned to threads managed by the stream processing topology. The threads are responsible for running the tasks, and they can be increased or decreased to adjust the parallelism of the stream processing.
2. Threading Model
The threading model in Kafka Streams is responsible for managing the threads that are used to run the tasks. It uses a master thread and a set of worker threads. The master thread manages the worker threads and assign tasks to them. The worker threads are responsible for running the tasks and processing the data.
It supports both fixed and dynamic threading. In fixed threading, the number of threads is fixed and does not change. In dynamic threading, the number of threads can be increased or decreased depending on the load.
3. Local State Stores
Kafka Streams provide support for local state stores, which are used to store application state data. The state stores provide a mechanism for preserving the state of an application in the event of a crash or shutdown. They also enable applications to maintain state across multiple partitions.
The local state stores are stored in memory, and they are shared across all the nodes in the cluster. The state stores can be used to store application data, such as counters, and they can be used to store intermediate results of processing.
4. Fault Tolerance
Kafka Streams provide fault-tolerance features to ensure that applications continue to run reliably in the event of node failures or network partitions. It uses two types of fault tolerance: at least once processing and exactly-once processing.
At least once processing ensures that each record is processed at least once, even in the event of a failure. It is the default setting in Kafka Streams and is suitable for most applications.
Exactly-once processing ensures that each record is processed only once, even in the event of a failure. It is more reliable than at-least-once processing, but it is more expensive and complex to implement.
Key Concepts of Kafka Streams
Now, let's discuss on few critical points of Kafka Streams! We will list each and try to understand each key separately.
1) Time
In Kafka Streams, time is used to represent the ordering of records in the stream. Records are assigned a timestamp when they are ingested into Kafka Streams, and this timestamp is used to determine the order of the records.
Time-based operations, such as window aggregations, can be used to group records together based on their timestamp.
2) SerDes
SerDes stands for serialiser and deserialiser, and they are used to convert between the binary and object formats of data in Kafka Streams. SerDes is used to serialise data into binary format when it is written to Kafka and deserialise data into object format when it is read from Kafka.
3) DSL Operations
Kafka Streams provides a set of DSL operations that can be used to transform and aggregate data. These operations are based on the Apache Kafka Streams API, and they provide an intuitive, declarative way to process data.
For example, the map operation can be used to transform records, and the reduced operation can be used to aggregate records.
4) Window Aggregations
Window aggregations are used to group records together based on their timestamps. Window aggregations can be used to compute statistics over a time window, such as the average of a field over the last hour.
Window aggregations can also be used to group records for further processing, such as joining two streams together.
5) Processing Model
The processing model in Kafka Streams is based on the concept of streaming. Records are ingested into Kafka Streams and processed as soon as they arrive. This allows applications to process data in real-time, which is an essential feature in many applications.
Scaling Kafka Streams
Kafka Streams provides several features that make it well-suited for scaling applications. It is horizontally scalable, meaning it can be scaled out to handle more traffic or process more data. It is fault-tolerant, meaning it can recover from failures without data loss.
Additionally, Kafka Streams is designed to run in the cloud and can be easily deployed on cloud-based services such as Amazon AWS, Google Cloud Platform, and Microsoft Azure.
Kafka Streams also provide built-in support for fault tolerance and scalability. It offers several options for parallelising data processing, such as using multiple partitions or threads. Additionally, it makes use of Kafka's distributed log structure to store data, which allows it to maintain consistency across multiple nodes in a cluster.
Interactive Queries
Kafka Streams also provides a feature called Interactive Queries, which allows developers to query the state of the application in real-time. This feature allows developers to obtain data from the application without writing custom code or accessing the underlying data store directly.
This is useful for applications requiring real-time data access, such as monitoring applications or dashboards.
The Interactive Queries feature powered by a distributed in-memory key-value store. This key-value store is replicated across Kafka Streams nodes and can be used to store stateful data. The key-value store is accessible through a REST API, which allows developers to query the data in real time.
Stream Threading
Kafka Streams also support stream threading, allowing developers to create multiple threads to process data streams in parallel. This is useful for applications that need to process data quickly and in parallel, such as applications that require real-time analytics.
Stream threading is implemented using a thread pool, which is a collection of threads that can be used to process data streams in parallel. Each thread in the thread pool is assigned a task and the threads are allocated resources such as memory and CPU time to process the tasks.
This allows Kafka Streams to process data streams quickly and efficiently.
Stream-Table Duality
Kafka Streams provides a feature called stream-table duality, which allows developers to store data in both a stream and a table. This is useful for applications that require both real-time access to data and the ability to query the data from a table.
The stream-table duality feature is implemented using Kafka Streams' internal key-value store. This key-value store can be used to store both streams and tables and is replicated across Kafka Streams nodes to provide fault tolerance.
The key-value store is also accessible through a REST API, which allows developers to query the data in real time.
What is the Kafka Streams API?
The Kafka Streams API is an open-source application programming interface (API) that developers can use to build streaming applications with Apache Kafka.
The Kafka Streams API allows developers to create custom streaming applications that process data from one or more topics in Apache Kafka and produce output on one or more topics.

How to Use Kafka Streams?
1) What is a Stream? – Table and Stream Mechanism
A stream is a continuous flow of data that is processed as it arrives. This can be compared to a table in a database, which is static and does not change until it is updated. Streams are processed as soon as the data arrives, allowing for real-time data processing.
Kafka Streams takes advantage of this stream processing by allowing developers to quickly and easily process data as it arrives. It uses a stream processing library to provide an API for developers to build applications that can process streaming data.
2) Topic Partitioning
Partitioning is an essential concept in Kafka Streams. It allows data to be partitioned across multiple nodes in a cluster, allowing for high scalability and fault tolerance. Partitioning also allows for better data locality and lower latency.
Partitioning is done by assigning each topic a unique identifier. This identifier is used to identify the topic and its corresponding partitions. The data within each partition is stored in order, allowing for efficient processing.
