A Presto client for the Go programming language, adapted from github.com/trinodb/trino-go-client.
This library strips out some of the more advanced Trino-specific functionality (such as the advanced type-scanning logic) and adapts it to work with Presto. This library also works with Trino when configured in Presto-compatibility mode, per the docs here.
Note that this driver aims to be compliant with the database/sql
package interface. In particular, only valid driver.Value
types are returned. The driver therefore behaves as documented in the
Rows.Scan documentation.
In particular, MAP, ARRAY, and ROW types are all returned as strings
containing serialized JSON. This differs from the upstream Trino driver, which
returns map[string]interface{} for MAP types and []interface{} for
ARRAY/ROW types (and is therefore non-compliant with the driver.Value
interface requirements).
Note that all date and time types are also returned as strings to maintain the precise format in which they're returned from Presto/Trino itself.
