Presto API Reference Guide

This page describes the presto (Presto data sources) endpoint.

Additional fields may be included in some responses you receive; however, these attributes are for internal purposes and are therefore undocumented.

Presto workflow

Create a data source

**Duplicate data sources**: In order to avoid two data sources referencing the same table, users can not create duplicate data sources. If you attempt to create a duplicate data source using the API, you will encounter a warning stating "duplicate tables are specified in the payload."

POST /presto/handler

Save the provided connection information as a data source.
