HTTP client properties#

HTTP client properties allow you to configure the connection from Trino to external services using HTTP.

The following properties can be used after adding the specific prefix to the property. For example, for OAuth 2.0 authentication, you can enable HTTP for interactions with the external OAuth 2.0 provider by adding the prefix oauth2-jwk to the http-client.connect-timeout property, and increasing the connection timeout to ten seconds by setting the value to 10:

oauth2-jwk.http-client.connect-timeout=10s

The following prefixes are supported:
