Achieving high availability is critical for ensuring the reliability and availability of Kafka-based applications. Here are some of the ways that you can achieve high availability in Kafka: 1. Replication: Kafka uses replication to ensure high availability and fault tolerance of data. Each partition in Kafka can have multiple replicas, with one replica designated as … Read more
Kafka MirrorMaker is a tool for replicating Kafka topics between two or more Kafka clusters. It is used to create a backup or a replica of a Kafka cluster, or to distribute data across multiple Kafka clusters for load balancing or other purposes. MirrorMaker works by consuming messages from a source Kafka cluster and producing … Read more
The Kafka Coordinator is a component of the Kafka consumer group that is responsible for managing the group’s state and coordinating the distribution of messages among the members of the group. The role of the Kafka Coordinator is critical for ensuring that messages are processed efficiently and effectively within Kafka-based applications. Here are some of … Read more
Kafka uses partitioning to handle message routing within a Kafka cluster. Kafka partitions allow messages to be distributed across multiple brokers in a way that enables efficient parallel processing and high availability. When a message is produced to a Kafka topic, it is assigned to a specific partition based on the partitioning strategy configured for … Read more
Kafka provides several security features to ensure that data is transmitted and processed securely within Kafka-based applications. Here are some of the key security features provided by Kafka: 1. Authentication: Kafka supports authentication using a variety of mechanisms, including Kerberos, SSL/TLS, and SASL. Authentication ensures that only authorized users and systems can access Kafka clusters … Read more
Kafka provides built-in support for data compression and serialization, which are important features for efficient and flexible data processing in Kafka-based applications. Data Compression: Kafka supports several data compression algorithms, including GZip, Snappy, and LZ4. Data compression is performed on the producer side, before the data is sent to Kafka. Compressed messages are stored in … Read more
The Kafka Controller is a key component of the Kafka broker cluster that is responsible for managing the state of the cluster and ensuring high availability and fault tolerance. The role of the Kafka Controller is to coordinate the activities of the brokers in the cluster, monitor their health, and manage the partition reassignment process. … Read more
Monitoring Kafka performance and health is critical for ensuring the reliability and availability of Kafka-based applications. Here are some of the ways that you can monitor Kafka performance and health: 1. Kafka metrics: Kafka provides a rich set of metrics that can be used to monitor the performance and health of Kafka clusters. These metrics … Read more
Kafka Streams windowing is a feature of the Kafka Streams library that allows developers to group and process data based on time windows or other logical windows. Windowing is a powerful feature that enables real-time aggregations and calculations over a sliding window of data, making it well-suited for use cases that require real-time data processing … Read more
Kafka and RabbitMQ are both popular messaging and streaming platforms that are used for building distributed systems. Although they share some similarities, there are several key differences between the two platforms. 1. Architecture: Kafka is designed as a distributed log-based messaging system, where messages are stored in logs and processed in batches. RabbitMQ, on the … Read more
