AWS Glue Data Catalog Client for Apache Hive Metastore 项目推荐
aws-glue-data-catalog-client-for-apache-hive-metastore The AWS Glue Data Catalog is a fully managed, Apache Hive Metastore compatible, metadata repository. Customers can use the Data Catalog as a central repository to store structural and operational metadata for their data. AWS Glue provides out-of-box integration with Amazon EMR that enables customers to use the AWS Glue Data Catalog as an external Hive Metastore. This is an open-source implementation of the Apache Hive Metastore client on Amazon EMR clusters that uses the AWS Glue Data Catalog as an external Hive Metastore. It serves as a reference implementation for building a Hive Metastore-compatible client that connects to the AWS Glue Data Catalog. It may be ported to other Hive Metastore-compatible platforms such as other Hadoop and Apache Spark distributions 项目地址: https://gitcode.com/gh_mirrors/aw/aws-glue-data-catalog-client-for-apache-hive-metastore
1. 项目基础先容与主要编程语言
本项目是由AWS labs团队开源的AWS Glue Data Catalog Client for Apache Hive Metastore，它是一个用Java语言编写的开源项目。该项目的目的是为了提供一个Apache Hive Metastore兼容的客户端，使得用户可以在Amazon EMR集群上使用AWS Glue Data Catalog作为外部Hive Metastore。
2. 项目的核心功能
AWS Glue Data Catalog是一个完全托管的、与Apache Hive Metastore兼容的元数据存储库。用户可以利用数据目次作为中心存储库，存储数据的布局性和操作性元数据。该项目的核心功能包括：
- 实现了Apache Hive Metastore客户端，可以在Amazon EMR集群上使用AWS Glue Data Catalog作为外部元数据存储。
- 作为构建与AWS Glue Data Catalog兼容的Hive Metastore客户端的参考实现。
- 支持将客户端移植到其他Hive Metastore兼容的平台，如其他Hadoop和Apache Spark发行版。
- 支持Spark 3和Hive 3。
3. 项目迩来更新的功能
根据项目的更新日记，迩来更新的功能主要包括：
- 优化了客户端的构建和配置流程，提供了更具体的指南。
- 支持客户端侧缓存，包括表元数据和数据库元数据的缓存，以提高查询效率。
- 对缓存策略进行了增强，用户可以自界说缓存大小和过期时间。
- 修复了一些已知的bug，并提高了客户端的稳定性和性能。
通过这些更新，项目为用户提供了更加便捷的构建和配置体验，同时也提升了元数据处理的效率。
