Kylin
Kylin is a distributed OLAP engine designed for executing fast SQL queries on massive datasets. It utilizes multi-dimensional data cubes to pre-calculate data aggregates, enabling sub-second response times for large-scale analytical queries and big data analytics.
The system focuses on large-scale data warehousing and multi-dimensional data modeling. It allows for the organization and querying of vast amounts of structured data to support business intelligence and reporting workflows through distributed SQL querying.
Features
- Cubes - Utilizes a pre-computed cube architecture to convert complex analytical queries into simple lookups for sub-second responses.
- Big Data and Analytics - Provides a comprehensive platform for running complex SQL commands and analyzing massive datasets across distributed systems.
- Data Warehousing - Provides a platform for large-scale data storage and high-performance analytical query execution to support business intelligence.
- Hadoop - Persists massive datasets and pre-computed cubes on the Hadoop distributed file system for scalability.
- Distributed SQL Querying - Provides a distributed engine to execute relational SQL queries and transformations on structured data across a cluster.
- Data Cubes - Pre-calculates data aggregates into multi-dimensional cubes to provide sub-second response times for large-scale queries.
- Multi-Dimensional Analysis - Executes complex analytical queries on large datasets using a distributed engine for high-speed responses.
- OLAP Database Engines - Operates as a distributed database optimized for high-performance multi-dimensional analytics and read-heavy workloads.
- Distributed Schema Management - Tracks data definitions and cube specifications in a relational database to coordinate distributed query execution.
- Dimensional Data Modeling - Structures data into facts and dimensions via cubes to optimize for analytical querying and reporting.
- Multi-Dimensional Data Indexing - Maps high-cardinality dimensions to physical storage locations to minimize data scanning during retrieval.
- Cube Translation - Converts standard SQL queries into a specialized internal format that targets pre-computed data slices.
