Apache Hive vs Apache Kylin

Apache Hive is a distributed data warehouse system for reading, writing, and managing large datasets with SQL. Its Metastore keeps shared metadata for tables and partitions and serves clients including Hive, Impala, and Spark; HiveServer2 supports concurrent clients through JDBC and ODBC. Hive provides full ACID transactions for ORC tables and insert-only transactions for other formats. Documented storage options include S3, Azure Data Lake, and Google Cloud Storage, and Hive supports Apache Iceberg tables through a StorageHandler. Named integrations include Spark, Presto, and Impala, with Apache Ranger for authorization and Apache Atlas for lineage and governance. Security options described by the project include Kerberos, fine-grained access control, and audit logging; HiveServer2 also lists LDAP, PAM, and custom authentication. The quickstart includes Docker instructions for the server and Metastore. Hive is free open-source software. The installation manual lists Java 8, Maven 3.6.3, Protobuf 2.5, Hadoop 3.3.6, and Tez among current prerequisites; Hive 4.2.x instead requires JDK 21 minimum and works with Hadoop 3.4.1 and Tez 0.10.5.

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.
