数据湖的元数据系统:模型和功能

Metadata Systems for Data Lakes: Models and Features

Pegdwendé Sawadogo, Etienne Scholly, Cécile Favre, Eric Ferey, Sabine Loudcher, Jérôme Darmont

摘要:

在过去的十年中,数据湖概念已经成为数据仓库的替代品,用于存储和分析大数据。数据湖允许在没有任何预定义模式的情况下存储数据。因此,数据查询和分析依赖于一个高效、全面的元数据系统。然而,数据湖中的元数据管理仍然是一个当前的问题,评估其有效性的标准是或多或少不存在的。在本文中,我们介绍了MEDAL,一个通用的,基于图的数据湖中的元数据管理模型。我们还提出了数据湖元数据系统的评估标准,通过预期的功能列表。最终,我们表明,我们的方法是更全面的比现有的元数据系统。

英文摘要:

Over the past decade, the data lake concept has emerged as an alternative to data warehouses for storing and analyzing big data. A data lake allows storing data without any predefined schema. Therefore, data querying and analysis depend on a metadata system that must be efficient and comprehensive. However, metadata management in data lakes remains a current issue and the criteria for evaluating its effectiveness are more or less nonexistent.In this paper, we introduce MEDAL, a generic, graph-based model for metadata management in data lakes. We also propose evaluation criteria for data lake metadata systems through a list of expected features. Eventually, we show that our approach is more comprehensive than existing metadata systems.
