Ahana Description
What is Presto? Presto is a distributed, federated SQL query engine that runs on multiple machines. It allows interactive, ad-hoc analysis on large quantities of data. You can run Presto SQL queries against your data. PrestoDB allows you to query data wherever it is located, including Hive and AWS S3, Hadoop and Cassandra, as well as relational databases, NoSQL database, or proprietary data stores. Presto is an open-source engine that allows users to access multiple sources of data, allowing them to perform analytics across the entire organization. A complete Presto installation requires a coordinator and multiple workers. Queries are sent from clients such as the Presto client to the coordinator. The coordinator analyzes, plans, and executes Presto queries.
