What are Kafka keys for?
Usually, the key of a Kafka message is used to select the partition and the return value (of type int ) is the partition number. Without a key, you need to rely on the value which might be much more complex to process.20 May 2020
What exactly Kafka key capabilities Mcq?
3) What exactly Kafka does? A) A streaming platform has three key capabilities: Publish and subscribe to streams of records, similar to a message queue or enterprise messaging system. Store streams of records in a fault-tolerant durable way.
What is special about Kafka?
Kafka can handle a lot of data per unit of time. It also has low latency, which allows for the processing of data in a real-time mode. Apache Kafka is written in Scala and Java, but it is compatible with many other popular programming languages. Kafka is different from traditional message queues (like RabbitMQ).Kafka can handle a lot of data per unit of time.

What is Kafka topic example?
An example topic name could be "payments". Topics in Kafka are always multi-producer and multi-subscriber: a topic can have zero, one, or many producers that write events to it, as well as zero, one, or many consumers that subscribe to these events.
What is broker and topic in Kafka?
Brokers are the heart of Kafka Cluster and its connector to the outer words such as consumer, producer, confluent connector. Kafka Topic consists of multiple partitions distributed across Brokers.8 Jul 2016
How many topics are in Kafka?
The rule of thumb is that the number of Kafka topics can be in the thousands. Jun Rao (Kafka committer; now at Confluent but he was formerly in LinkedIn's Kafka team) wrote: At LinkedIn, our largest cluster has more than 2K topics. 5K topics should be fine.30 May 2020
Is Kafka queue or topic?
A Kafka topic is sub-divided into units called partitions for fault tolerance and scalability. Consumer Groups allow Kafka to behave like a Queue, since each consumer instance in a group processes data from a non-overlapping set of partitions (within a Kafka topic).
Where is Kafka used for?
In short, Kafka is used for stream processing, website activity tracking, metrics collection and monitoring, log aggregation, real-time analytics, CEP, ingesting data into Spark, ingesting data into Hadoop, CQRS, replay messages, error recovery, and guaranteed distributed commit log for in-memory computing ( In short, Kafka is used for stream processing, website activity tracking, metrics collection and monitoring, log aggregation, real-timereal-timeReal-time data (RTD) is information that is delivered immediately after collection.

What is Kafka and how does it work?
Kafka is an open source software which provides a framework for storing, reading and analysing streaming data. Being open source means that it is essentially free to use and has a large network of users and developers who contribute towards updates, new features and offering support for new users.
What problem does Kafka solve?
Kafka came up with a solution to the problem with continuous streams of data, as there was no other solution at that moment that could handle such data flow. Kafka is a distributed streaming platform for building real-time data pipelines and real-time streaming applications.Kafka came up with a solution to the problem with continuous streams of data, as there was no other solution at that moment that could handle such data flow.

What Kafka is good for?
Kafka is primarily used to build real-time streaming data pipelines and applications that adapt to the data streams. It combines messaging, storage, and stream processing to allow storage and analysis of both historical and real-time data.Kafka is primarily used to build real-timereal-timeReal-time data (RTD) is information that is delivered immediately after collection.

Is Kafka an API gateway?
API gateway: Most API management tools do not provide native support for event streaming and Kafka today and only work on top of REST interfaces. Kafka (via the REST interface) and API management are still very complementary for some use cases, such as service monetization or integration with partner systems.18 Nov 2020
Is Kafka a REST API?
The Kafka REST Proxy is a RESTful web API that allows your application to send and receive messages using HTTP rather than TCP. It can be used to produce data to and consume data from Kafka or for executing queries on cluster configuration.6 Aug 2021
What is the difference between Kafka and REST API?
Kafka - Data is stored in topic. Seek back & forth (offsets) whenever you want till the topic is retained. REST - Once the response is over, it is over. Manually employ a database to store the processed data.9 Sept 2019
