Apache ZooKeeper is a distributed coordination service used by Arenadata Streaming to manage the configuration and coordination of its clusters. It is a crucial component of the system as it helps to ensure high availability and fault tolerance in Arenadata Streaming clusters.

ZooKeeper provides a hierarchical namespace that allows Arenadata Streaming to store configuration data, manage distributed locks, and coordinate distributed processes. It provides a consistent view of the system state across all nodes in the cluster, which helps to prevent data inconsistencies and ensure data integrity.

For example, Arenadata Streaming uses ZooKeeper to manage its Kafka brokers, topics, and partitions. When a new broker is added to the cluster, ZooKeeper is used to assign it a unique identifier and to coordinate the distribution of data across the cluster.

Apache Kafka is a distributed streaming platform used by Arenadata Streaming to manage the ingestion, processing, and analysis of real-time data streams. It provides a scalable, fault-tolerant, and highly available infrastructure for processing and storing real-time data.

Arenadata Streaming leverages Kafka's capabilities to handle large volumes of data and support multiple data sources. It provides a real-time data processing platform that enables businesses to analyze data as it flows through the system, providing near-instant insights into business operations.

Schema Registry is a centralized repository used by Arenadata Streaming to store and manage schemas for data produced and consumed by Apache Kafka. It allows users to define, evolve, and share schemas across different applications and systems that use Kafka.

In Arenadata Streaming, Schema Registry enables users to ensure data compatibility across different versions of their applications and systems. It provides a way to enforce data validation and to ensure that all data produced and consumed by Kafka conforms to a predefined schema.

KSQL is a streaming SQL engine used by Arenadata Streaming to process real-time data streams. It allows users to write SQL queries to transform, aggregate, and analyze data in real-time, making it easy to create real-time data processing pipelines without the need for complex programming.

In Arenadata Streaming, KSQL provides a simple yet powerful way to interact with data streams, enabling users to query, join, and filter data as it flows through the system. It supports a wide range of SQL operations, including windowing, aggregations, and joins, allowing users to create complex processing logic without the need for custom code.

Kafka Connect is a data integration framework used by Arenadata Streaming to move data between Apache Kafka and other systems. It provides a scalable and fault-tolerant infrastructure for ingesting and exporting data to and from Kafka, making it easy to integrate different systems and technologies with Kafka.

In Arenadata Streaming, Kafka Connect enables users to integrate data from various sources such as databases, file systems, and messaging systems with Kafka. It provides connectors that can be configured to extract data from different systems and write it to Kafka topics, or to read data from Kafka topics and write it to external systems.

It is also used for MirrorMaker 2. MirrorMaker 2 is a tool used by Arenadata Streaming to replicate data between Apache Kafka clusters. It is a replacement for the original MirrorMaker tool and provides several new features and improvements over its predecessor.

Kafka REST Proxy is a tool used by Arenadata Streaming to expose Apache Kafka functionality as a RESTful API. It provides a simple and scalable way to integrate Kafka with other systems and technologies that support RESTful APIs.

Apache NiFi is an open-source data integration tool used by Arenadata Streaming to automate the flow of data between different systems and technologies. It provides a visual drag-and-drop interface for designing and configuring data flows, making it easy for users to build complex data pipelines without writing any code.

In Arenadata Streaming, Apache NiFi enables users to build and manage data flows across different systems and technologies. It provides a wide range of processors and connectors that can be used to integrate with various data sources and destinations, including databases, message queues, and cloud platforms.

Apache MiNiFi is a lightweight data collection tool used by Arenadata Streaming to collect and preprocess data at the edge of the network. It is designed to run on resource-constrained devices, such as sensors and IoT devices, and enables users to collect and process data in real-time, without relying on a central server.

In Arenadata Streaming, Apache MiNiFi enables users to collect and preprocess data at the edge of the network, before sending it to a central server for further processing and analysis. It provides a wide range of processors and connectors that can be used to collect data from various sources, including sensors, cameras, and other IoT devices.

Apache NiFi Registry is a version control and management system used by Arenadata Streaming to manage and version data flows and other assets created using Apache NiFi. It provides a central repository for storing and managing NiFi flows, templates, and other artifacts, enabling users to easily version, deploy, and reuse them across different environments.

Kafka Manager (also known as CMAK) is a web-based management tool used to manage Apache Kafka clusters. It is designed to simplify the administration of Kafka clusters, providing a user-friendly interface for managing and monitoring Kafka topics, partitions, and brokers.

In Arenadata Streaming, Kafka Manager enables users to easily manage and monitor their Kafka clusters. It provides a web-based interface for performing administrative tasks, such as creating and deleting topics, reassigning partitions, and managing broker configurations. It also provides real-time metrics and monitoring of Kafka clusters, allowing users to easily identify and troubleshoot issues.
