Best Practices for Managing Open Data on a Data Lakehouse Platform
Managing open data on a data lakehouse platform requires careful attention to data governance, metadata management, data access, and data quality. These areas are critical for effectively managing and utilizing open data to gain insights and make data-driven decisions. By implementing best practices in these areas, organizations can ensure that open data is compliant with legal and ethical regulations, properly documented, easily discoverable, accessible to authorized users, and of high quality.
Data Governance
In open data lakehouses, data governance ensures that open data is compliant with legal and ethical regulations, is secure, and is of high quality. This includes establishing data access controls, data classification, and data retention policies.
Metadata Management
Metadata management ensures that open data is properly documented, discoverable, and accessible to others. It helps describe the characteristics and properties of data, including where it came from, who owns it, and how it can be used.
Data Access and Sharing
Data access policies should be established to ensure that open data is accessible to authorized users and stakeholders while protecting sensitive information. Data-sharing policies should encourage collaboration and innovation while maintaining the privacy and security of open data.
Data Quality and Lineage
Data quality and data lineage ensure the accuracy, completeness, consistency, and reliability of open data by tracking data history from creation to the current state. By ensuring data quality and tracking data lineage, organizations can ensure that open data is trustworthy and reliable.
Open Data Lakehouse Platforms
There are several common open data lakehouse platforms that organizations can use to manage and analyze open data. These platforms provide a comprehensive solution for storing, processing, and analyzing large volumes of data from a variety of sources.
Apache Iceberg
One common open data lakehouse platform is Apache Iceberg, which provides a scalable and flexible platform for managing data in a cloud environment. Apache Iceberg supports multiple data formats, including Parquet and ORC, and provides a SQL interface for querying data.
Delta Lake
Another common open data lakehouse platform is Delta Lake, which is built on top of Apache Spark and provides ACID transactions and schema enforcement for data stored in a data lake. Delta Lake also provides data versioning and data lineage capabilities, making it easier to track changes to data over time.
Apache Hudi
Apache Hudi is another open data lakehouse platform that provides data storage and processing capabilities for big data in a distributed environment. Apache Hudi supports real-time data ingestion and processing and provides features for data lifecycle management, data quality, and data access control.
There are several open data lakehouse platforms available, each with their own set of features and capabilities. By choosing the right platform for their needs, organizations can effectively manage and analyze open data to gain insights and make data-driven decisions.
