# JDBC parameters

Reference for the e6data JDBC connection URL and its parameters.

The e6data JDBC driver connects over gRPC to the workspace endpoint on port `443` (TLS). The cluster is selected by a connection parameter, so the host stays the same across all your clusters. For setup, see [JDBC](/query-engine/developers/connecting-to-the-engine/jdbc.md).

## Connection URL

```
jdbc:e6data://<HOST>:443/secure=true&cluster-name=<CLUSTER>&catalog=<CATALOG>&database=<SCHEMA>
```

## Parameters

| Parameter      | Required    | Description                                                    |
| -------------- | ----------- | -------------------------------------------------------------- |
| `cluster-name` | Yes         | The cluster to route queries to.                               |
| `catalog`      | Yes         | The catalog to query.                                          |
| `database`     | Yes         | The schema (database) within the catalog.                      |
| `secure`       | Yes         | `true` to use TLS (always on for authenticated clusters).      |
| `cluster-uuid` | Conditional | Required when connecting through a TLS connectivity endpoint.  |
| `AUTO_RESUME`  | No          | `true` to allow the first query to resume a suspended cluster. |

## Authentication

| Field    | Value                                                                                                  |
| -------- | ------------------------------------------------------------------------------------------------------ |
| Username | your e6data email                                                                                      |
| Password | a [personal access token](/query-engine/guides/security/access-tokens/pat-and-service-account-keys.md) |

The JDBC driver class and the driver download are shown in the Console under **Cluster → Connectivity**. The driver also supports browser-based SAML SSO for interactive use.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.e6data.com/query-engine/reference/connectivity-reference/jdbc-parameters.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
