The description you provided pertains to Presto, an open-source federated, distributed SQL query engine designed for use with the Open Data Lakehouse architecture. Here’s a breakdown of the key points mentioned:
Presto: Presto is described as an open-source SQL query engine that can query data wherever it resides. It is particularly well-suited for querying data in a distributed and federated manner, making it a versatile tool for data analytics.
Presto Sandbox: The description mentions the availability of a Presto Sandbox, which appears to be a environment for users to get started with Presto quickly. This sandbox includes essential components such as the presto-cli for executing queries.
Hive Metastore: The Presto Sandbox includes a Hive Metastore backed by PostgreSQL. The Hive Metastore is a catalog for storing metadata about data stored in a data lake or data warehouse. It plays a crucial role in managing metadata and table schemas.
Additional Catalogs: The Presto Sandbox also bundles additional catalogs like TPC-DS and TPC-H. These catalogs provide schemas and data to support benchmarking using the TPC-DS and TPC-H benchmarks. Users can use these catalogs to test and prototype Presto queries.
Ahana Cloud Community Edition: An alternative to using the Presto Sandbox AMI is mentioned. Users are directed to the Ahana Cloud Community Edition, a managed service for Presto on AWS. This service includes features like a managed Presto service, a Hive metadata catalog, data sources (including S3), and basic business intelligence (BI) support using Apache Superset. It is positioned as a convenient way to set up and manage Presto in an Open Data Lakehouse architecture on AWS.
Contact Information: The description provides contact information (hello@ahana.io) for users who want to learn more about how Ahana can help support their Presto deployment.
In summary, the Presto Sandbox is introduced as a way for users to quickly and easily get started with Presto for querying data in a federated and distributed manner. Users can also explore an alternative, managed solution for Presto deployment on AWS through Ahana Cloud Community Edition.
