What type of system is Kafka?
Kafka is a distributed system consisting of servers and clients that communicate via a high-performance TCP network protocol.
What should you not use with Kafka?
Avoid using Kafka for ETL jobs, especially where real-time processing is needed. When you need to use a simple task queue you should use appropriate instruments. Kafka is not designed to be a task queue. There are other tools that are better for such use cases — for example, RabbitMQ.
Which format is supported by Kafka?
Supported Formats
| Format | Producer | Consumer |
|---|---|---|
| ProtoBuf | io.confluent.kafka.serializers.protobuf.KafkaProtobufSerializer | io.confluent.kafka.serializers.protobuf.KafkaProtobufDeserializer |
| JSON Schema | io.confluent.kafka.serializers.json.KafkaJsonSchemaSerializer | io.confluent.kafka.serializers.json.KafkaJsonSchemaDeserializer |
Does Kafka use TCP?
Kafka uses a binary protocol over TCP. The protocol defines all APIs as request response message pairs.
How Kafka works in Microservices?
A Kafka-centric microservice architecture refers to an application setup where microservices communicate with each other using Kafka as an intermediary. This is made possible with Kafka’s publish-subscribe model for handling the writing and reading of records.
How many partitions should I have Kafka?
For most implementations you want to follow the rule of thumb of 10 partitions per topic, and 10,000 partitions per Kafka cluster. Going beyond that amount can require additional monitoring and optimization. (You can learn more about Kafka monitoring here.)
Does Kafka need Java?
NOTE: Your local environment must have Java 8+ installed. Once all services have successfully launched, you will have a basic Kafka environment running and ready to use.
What data format is Kafka?
The continuous data collection (CDC) Kafka data is the CDC data that real-time runtime metrics collection collects, transforms to JSON format, and sends to Apache Kafka.
