{% hint style="info" %} The Dremio connection is compatible with JDK11 if you add the following to owlmanage.sh as a JVM option for the web and Spark instance: `-Dcdjd.io.netty.tryReflectionSetAccessible=true` {% endhint %} ## Minimum user permissions In order to bring your Dremio data into Data Quality & Observability (self-hosted), you need the following permissions. * Read access on your Dremio tables. * ROLE\_ADMIN assigned to your user in Collibra DQ. ## Recommended and required connection properties | Required | Connection Property | Type | Value | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Yes | Name | Text | The unique name of your connection. Ensure that there are no spaces in your connection name. | | Yes | Connection URL | String |

The connection string path of your Dremio connection.

When referring to the example below, replace the ${value} sections of the connection URL with your actual value.

jdbc:dremio:direct=${host};schema=Samples

| | Yes | Driver Name | String |

The driver class name of your Dremio connection.

com.dremio.jdbc.Driver

| | Yes | Port | Integer |

The port number to establish a connection to the datasource.

The default port is 31010

| | No | Limit Schemas | Option |

Allows you to manage usage and restrict visibility to only the necessary schemas in the Explorer tree.

See Limiting schemas to learn how to limit schemas from the Connection Management page.

When you include a restricted schema in the query of a DQ Job, the query scope may be overwritten when the job runs. While only the schemas you selected when you set up the connection are shown in the Explorer menu, users are not restricted from running SQL queries on any schema from the data source.

| | No | Source Name | String | N/A | | No | Target Agent | Option | The [Agent](/data-quality-self-hosted/installation/agent.md) that submits your Spark job for processing. | | Yes | Auth Type | Option |

The method to authenticate your connection.

The configuration requirements are different depending on the Auth Type you select. See Authentication for more details on available authentication types.

| | No | Properties | String | The configurable driver properties for your connection. Multiple properties must be semicolon-delimited, and each property=value pair, including the last one, must end with a semicolon (;). `abc=123;test=true;` | ## Authentication This data source supports the following authentication type: Username/Password | Required | Field | Description | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- | ------------------------------------ | | Yes | Username | The username of your Dremio account. | | Yes | Password | The password of your Dremio account. | ## Known limitations * When you run a DQ job with a SQL query that attempts to perform a WHERE on a date column, the job fails. For example, `select * from "@admin"."myspace" WHERE registration_dttm = '2016-02-03T07:55:29'`. There is currently no known workaround for this limitation. * When you run a DQ job with a SQL query that does not contain an explicit WHERE clause, the job fails with an exception message that the command line does not contain a `-rd`. A workaround for this limitation is to add WHERE 1=1 to the query. * When you run a DQ job with a query that contains both a WHERE and LIMIT clause, the SQL preview returns all records and ignores both filters.
