What is Kylin?

Kylin is an open-source distributed analytics engine specifically designed for big data. Developed by eBay Inc., Kylin was later open-sourced and donated to the Apache Software Foundation, making it available to a wider community of users and contributors. This powerful OLAP engine combines the strengths of Hadoop and Apache Kylin to deliver lightning-fast query performance on large-scale datasets.

Accelerating Query Performance

One of Kylin’s key advantages is its ability to significantly accelerate query performance. Traditional OLAP systems often struggle with complex analytical queries on large datasets, resulting in long wait times and inefficient resource utilization. Kylin addresses these challenges by leveraging pre-calculated data cubes and a multi-dimensional data model, enabling sub-second query response times even on petabyte-scale datasets.

Distributed Architecture

Kylin’s distributed architecture plays a crucial role in its ability to process and analyze large volumes of data. By utilizing Hadoop’s distributed computing capabilities, Kylin allows for horizontal scalability, enabling organizations to seamlessly scale their analytics infrastructure as their data grows. This distributed approach not only enhances performance but also ensures fault tolerance and high availability, crucial for mission-critical applications.

Seamless Integration with Existing Ecosystem

One of the strengths of Kylin lies in its seamless integration with existing big data ecosystems. Organizations can leverage Kylin’s compatibility with various data sources such as Apache Hadoop, Apache Hive, and Apache Spark. This flexibility enables businesses to build on their existing infrastructure investments, eliminating the need for costly and time-consuming data migrations.

Key Features of Kylin

Cubing and Pre-computation

Kylin’s core feature is its ability to generate pre-calculated data cubes. These cubes provide aggregated views of the data, allowing for faster query response times. By pre-computing the results of common analytical queries, Kylin reduces the need for extensive data scanning, enabling real-time data exploration and analysis.

Query Optimization

Kylin employs a range of query optimization techniques to enhance query performance. It leverages statistics, indexes, and data partitioning to optimize query execution plans, ensuring efficient resource utilization. Additionally, Kylin supports advanced query features such as aggregations, filters, and sorting, further enhancing the analytical capabilities of the engine.

Real-Time Data Refresh

Kylin offers real-time data refresh capabilities, allowing organizations to continuously update their data cubes with minimal latency. This ensures that users have access to the most up-to-date insights, empowering them to make timely decisions based on the latest information. The real-time data refresh feature eliminates the need for manual cube rebuilds, saving valuable time and resources.

Security and Access Control

Data security is a critical aspect of any analytics solution. Kylin provides robust security features, including fine-grained access control and authentication mechanisms. Organizations can define access privileges at the user, group, or project level, ensuring that sensitive data remains protected. Additionally, Kylin integrates with existing authentication systems, simplifying user management and access control.

Use Cases for Kylin

E-commerce Analytics

Kylin’s high-performance capabilities make it an ideal choice for e-commerce analytics. Online marketplaces generate vast amounts of transactional data, which require real-time analysis to identify trends, optimize pricing strategies, and personalize customer experiences. Kylin’s ability to process complex analytical queries on large-scale datasets enables e-commerce businesses to gain valuable insights from their data, driving revenue growth and customer satisfaction.

Financial Analysis

Financial institutions deal with enormous volumes of data, including transaction records, market data, and customer profiles. Kylin’s fast query response times and support for complex calculations make it a valuable tool for financial analysis. From risk assessment and fraud detection to portfolio optimization and regulatory compliance, Kylin empowers financial organizations to gain deeper insights into their data, facilitating informed decision-making and mitigating risks.

IoT Analytics

With the proliferation of Internet of Things (IoT) devices, organizations are faced with the challenge of analyzing massive streams of real-time data. Kylin’s ability to handle high-velocity data and deliver near real-time query responses makes it an excellent choice for IoT analytics. Whether it’s monitoring sensor data, predicting equipment failures, or optimizing resource allocation, Kylin enables organizations to extract valuable insights from their IoT data, driving operational efficiency and innovation.


Kylin, the next generation OLAP engine, has emerged as a game-changer in the field of big data analytics. With its lightning-fast query performance, distributed architecture, and seamless integration with existing ecosystems, Kylin empowers organizations to unlock the full potential of their data. By harnessing the power of pre-computed data cubes, query optimization techniques, and real-time data refresh capabilities, businesses can gain valuable insights and make data-driven decisions with unparalleled speed and accuracy. Whether it’s e-commerce, finance, or IoT analytics, Kylin stands as a powerful tool that propels organizations to stay ahead in today’s data-driven world.
