6.5. Querying Presto#
Any query has to be submitted to the coordinator for processing on the cluster. Typically you need the following parameters to connect:
coordinator host name such as
protocol HTTP, defaults to port 80, or HTTPS, defaults to port 443
port, if non-default port is configured and exposed
Host name, protocol and port are configured by the service properties. Typically, a service name is defined and HTTPS is used.
Now you can use any client or driver supported by Presto to connect and query.
Example: Presto CLI#
You can use the Presto CLI from your local workstation:
Install the Presto CLI.
Use the parameters determined in the preceding section.
Run the CLI with URL and username supplied and activate the password dialog:
presto --server https://presto.example.com --user admin --password
Once connected you can check for available catalogs with
SHOW CATALOGS, or run any other query.
