Hive connector with Alluxio

The Hive connector can read and write tables stored in the Alluxio Data Orchestration System, leveraging Alluxio’s distributed block-level read/write caching functionality. The tables must be created in the Hive metastore with the alluxio:// location prefix (see Running Apache Hive with Alluxio for details and examples).

Trino queries will then transparently retrieve and cache files or objects from a variety of disparate storage systems including HDFS and S3.
