Hive Metastore
The metadata storage service of Apache Hive, providing centralized management of metadata such as table schemas and partitions. It is a widely used metadata standard protocol in the Hadoop ecosystem.
Timeline (last 90 days)
Currently, common open metadata standards in the industry include the Apache Iceberg REST Catalog specification, the Hive Metastore protocol, and the evolving Unity Catalog open API.
Object storage such as S3 only guarantees the atomicity of a single-object PUT, with no cross-object rename or transactions, so Iceberg's atomic commits on object storage rely on mechanisms such as rename, Hive Metastore database transactions, or the CAS of a REST catalog.
SqlDBM is a cloud-native, no-code data modeling platform that can connect directly to Databricks Unity Catalog and Hive Metastore.
The REST Catalog protocol is becoming the de facto industry standard, freeing the metadata management of Iceberg tables from being tied to specific catalog implementations such as Hive Metastore and AWS Glue
