-----------------------------------
Summary: Re implement a catalog based on file system for metadata
management
Key: HIVE-28621
URL: https://issues.apache.org/jira/browse/HIVE-28621
Project: Hive
Issue Type: New Feature
Security Level: Public (Viewable by anyone)
Components: Iceberg integration
Affects Versions: 4.1.0
Reporter: yongzhi.shao
Currently, the iceberg community has deprecated hadoop_catalog in version 1.7.0
and plans to remove it in future versions. However, the catalog management
solution based on the file system is actually very user-friendly. It is
lightweight, allowing users to minimize the dependencies required for startup.
Moreover, it is also very friendly for cross-engine operations on Iceberg
tables.
We have implemented a version of catalog management based on the file system
that can manage catalogs without relying on any third-party services and
without requiring the file system to provide rename operations. We have
verified its functionality in various file systems such as
HDFS/S3/LOCAL-POSIX/LOCAL-LINUX/WINDOWS, and it works well.
If we want to contribute it to the HIVE project, what should I do?
Additionally, I would like to know what the HIVE community's opinion is on
FS-CATALOG?
Tks.
