Data Warehousing

Cloudera Data Platform Runtime includes Apache Hive, Apache Iceberg, and Apache Impala for storing and accessing data in the Hive metastore database. Hive addresses enterprise data warehouse demands for transactional data in the ORC file format. Iceberg is a table format for huge analytics that you can query using familiar SQL statements. Impala performs high-performance, low-latency SQL queries on data in Parquet and other formats.
