What is Kafka REST API? The Kafka REST Proxy provides a RESTful interface to a Kafka cluster. It makes it easy to produce and consume messages, view the state of the cluster, and perform administrative actions without using the native Kafka protocol or clients.
What is Kafka API? The Kafka Streams API to implement stream processing applications and microservices. The Kafka Connect API to build and run reusable data import/export connectors that consume (read) or produce (write) streams of events from and to external systems and applications so they can integrate with Kafka.
Does Kafka use APIs? However for more complex transformations Kafka provides a fully integrated Streams API.
This allows building applications that do non-trivial processing that compute aggregations off of streams or join streams together.
How does Kafka rest work? The Kafka REST proxy allows developers not only to produce and consume data to/from a Kafka cluster with minimal prerequisites but also perform some administrative tasks such as overwriting offset commits or manually assigning partitions to consumers via simple HTTP requests, without the need to leverage native clients
What is Kafka REST API? – Related Questions
Can Kafka replace API?
You can use the APIs of Kafka and its surrounding ecosystem, including ksqlDB, for both subscription-based consumption as well as key/value lookups against materialised views, without the need for additional data stores.
The APIs are available as native clients as well as over REST.
Is Kafka pull or push?
With Kafka consumers pull data from brokers.
Other systems brokers push data or stream data to consumers.

Kafka like many pull based systems implements a long poll (SQS, Kafka both do).

Is Kafka a NoSQL database?
It stores streams of data safely in distributed and fault-tolerant.
I don’t understant that why we need NoSQL databases like as MongoDB to store same data in Apache Kafka.
In other ways, no: it has no data model, no indexes, no way of querying data except by subscribing to the messages in a topic.
Why is Kafka so fast?
Compression & Batching of Data: Kafka batches the data into chunks which helps in reducing the network calls and converting most of the random writes to sequential ones. It’s more efficient to compress a batch of data as compared to compressing individual messages.
Can Kafka replace Hadoop?

Can we use Kafka without zookeeper?
You can not use kafka without zookeeper. Mainly zookeeper is used to manage all the brokers. These brokers are responsible for maintaining the leader/follower relationship for all the partitions in kafka cluster.
Can Kafka run without Hadoop?
First, it will allow Kafka to use the computing and data resources of the Hadoop cluster. “Right now Kafka runs outside of Hadoop and because of that it’s not able to share the resources of the Hadoop cluster and the data is away from the Hadoop cluster,” Bari continues.
