Apache Kylin vs Trino

Apache Kylin is an open-source OLAP engine for data analytics, designed for large-scale workloads with many concurrent users. Its pre-calculation approach is intended to support sub-second SQL queries. Kylin 5 can build models from SQL text, suggest index changes using query history, and use Apache Gluten as a native compute engine; the product overview describes a 2–4× improvement compared with vanilla Spark. For mixed data workloads, it supports Kafka streaming sources and fusion models for batch and streaming analysis, as well as internal tables for flexible queries and lakehouse scenarios. Teams can connect Tableau, Power BI, or Excel. A web UI supports table management, model design, job execution, and configuration. Deployment offers query, job, or all server modes. Kylin runs on Linux and uses Spark with Yarn or Standalone mode. Data storage can use HDFS or S3-compatible systems, while MySQL or PostgreSQL can hold metadata. The project is free under Apache License v2, with source and binary packages available. APIs use Basic Authentication; HTTPS is supported in Kylin 5 but disabled by default.

Trino is a distributed SQL query engine for analytics across large datasets held in different systems. It supports ANSI SQL and can query multiple sources together, such as joining S3 object storage data with MySQL in one query. Its parallel, distributed design is intended for efficient, low-latency analytics and data warehousing, not general-purpose relational database use or OLTP workloads. Connectors cover systems including BigQuery, Cassandra, ClickHouse, Elasticsearch, MongoDB, MySQL, Oracle, PostgreSQL, Redis, Snowflake, and SQL Server. Project-maintained client options include JDBC, Go, JavaScript, Python, and C#, alongside a command-line interface and Grafana data-source plugin. Trino runs in Kubernetes or Docker, or as a manually deployed server, and is optimized for cloud and on-premises environments including Amazon, Azure, and Google Cloud. AI functions support OpenAI and Anthropic directly and other models through Ollama, with the language model supplied as an external service. Trino is free under the Apache License 2.0 as self-managed software. It supports multiple authentication and access-control options, but a default installation has no security features enabled.
