Access Live CockroachDB Data in Coginiti Pro

Coginiti Pro is a single tool for all your SQL data and analytics needs, designed specifically for data engineers, analysts, and data scientists. When paired with the CData JDBC Driver for CockroachDB, Coginiti Pro can access and query live CockroachDB data. This article describes how to connect to and query CockroachDB data from Coginiti Pro.

With built-in optimized data processing, the CData JDBC Driver for CockroachDB offers unmatched performance for interacting with live CockroachDB data. When you issue complex SQL queries to CockroachDB, the driver pushes supported SQL operations, like filters and aggregations, directly to CockroachDB and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). In addition, its built-in dynamic metadata querying allows you to work with and analyze CockroachDB data using native data types.

Gather Connection Properties and Build a Connection String

Download the CData JDBC Driver for CockroachDB installer, unzip the package, and run the JAR file to install the driver. Then gather the required connection properties.

Set the following to connect to CockroachDB.

• Server: The host name or IP address of the server.
• Port: The port number of the CockroachDB server. If not specified, the default port is 26257.
• Database: The name of the Cockroach database. If not specified, you connect to the user's default database.
• User: The Cockroach DB user account used to authenticate.
• Password: The password used to authenticate the user.
