Why is Kafka faster than RabbitMQ?
Kafka offers much higher performance than message brokers like RabbitMQ.
It uses sequential disk I/O to boost performance, making it a suitable option for implementing queues.
It can achieve high throughput (millions of messages per second) with limited resources, a necessity for big data use cases..
Is ZooKeeper a load balancer?
AWS Elastic Load Balancing (ELB) can be classified as a tool in the “Load Balancer / Reverse Proxy” category, while Zookeeper is grouped under “Open Source Service Discovery”.
Why does Kafka need ZooKeeper?
Zookeeper keeps track of status of the Kafka cluster nodes and it also keeps track of Kafka topics, partitions etc. Zookeeper it self is allowing multiple clients to perform simultaneous reads and writes and acts as a shared configuration service within the system.
What is Apache ZooKeeper used for?
ZooKeeper is an open source Apache project that provides a centralized service for providing configuration information, naming, synchronization and group services over large clusters in distributed systems. The goal is to make these systems easier to manage with improved, more reliable propagation of changes.
What happens if ZooKeeper goes down in Kafka?
For example, if you lost the Kafka data in ZooKeeper, the mapping of replicas to Brokers and topic configurations would be lost as well, making your Kafka cluster no longer functional and potentially resulting in total data loss.
Does Kafka include ZooKeeper?
Currently, Apache Kafka® uses Apache ZooKeeper™ to store its metadata. Data such as the location of partitions and the configuration of topics are stored outside of Kafka itself, in a separate ZooKeeper cluster. In 2019, we outlined a plan to break this dependency and bring metadata management into Kafka itself.
Does Kafka have 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.
How do I call Kafka REST API?
How to make REST API calls in kafka streams application/Start reading the input topic.Call mapvalues to make a database call and decorate the record with the additional data.Make a REST api call with the input request, get the response.Output the record in the kafka topic.
Is Kafka a database?
Apache Kafka is a database. … However, in many cases Kafka is not competitive to other databases. Kafka is an event streaming platform for messaging, storage, processing and integration at scale in real time with zero downtime and zero data loss.
Does Kafka consumer need ZooKeeper?
First of all, zookeeper is needed only for high level consumer. SimpleConsumer does not require zookeeper to work. The main reason zookeeper is needed for a high level consumer is to track consumed offsets and handle load balancing. … Here’s where zookeeper kicks in: it stores offsets for every group/topic/partition.
What is the relationship between Kafka and ZooKeeper?
Kafka uses Zookeeper to manage service discovery for Kafka Brokers that form the cluster. Zookeeper sends changes of the topology to Kafka, so each node in the cluster knows when a new broker joined, a Broker died, a topic was removed or a topic was added, etc.
What is Kafka REST API?
The Kafka REST API provides a RESTful interface to a Kafka cluster. You can produce and consume messages by using the API. For more information including the API reference documentation, see Kafka REST Proxy docs. . Only the binary embedded format is supported for requests and responses in Event Streams.
