Query Data

Hydrolix provides a number of query interfaces that can be used to interact with the system.

API

You can query your Hydrolix cluster via HTTP at https://<your-hostname>/query:

$ curl -XPOST https://try.hydrolix.net/query -d 'SELECT count() FROM sample_project.sample_table'

Native

The Native interface exposes your database to Clickhouse clients, including:

query-peer :) SELECT COUNT() FROM sample.performance_logs

SELECT COUNT()
FROM sample.performance_logs

Hydrolix UI

The Hydrolix UI queries your cluster from a browser using the HTTP API. This environment is good for cursory tests, but you should use alternative clients or 3rd Party Integrations for result sets larger than 10,000 rows.
