A fast and lightweight command line interface for the Apache Hive metastore.
Hive's metastore is ubiquitous in many big data deployments, whether the deployment in question makes use of the Hive execution engine or not. It is a common component that provides table virtualization for other distributed processing engines such as Flink, Spark and Trino.
More modern analytic table formats such as Iceberg and Hudi leverage Hive's metastore to some extent for the serving and storage layer of their metadata. Cloud data catalogs such as GCP's DataProc Metastore and AWS's Glue Data Catalog also implement the metastore interface.
Typically, operations against the metastore are done via these engines' catalog procedures, or in SQL DDL using the Hive Cli itself. There are limited options for calling the metastore's endpoints themselves directly. This project provides a lightweight command line interface to the metastore's Thrift endpoints directly, to allow lower-level debugging of metastore payloads without JVM startup overhead.
