Managing advanced settings

Cloudera Data Visualization allows users with administration privileges to configure several advanced settings.

Webhook

You can use webhooks to pass parameters to any API endpoint that you might want to update with a dashboard's parameters.

To interact with webhooks, check the Allow users to interact with webhooks option and enter the URLs in the URLs that webhook actions are permitted to interact with text box. If you add multiple values, separate them by a new line.

Remote data

To provide URLs for remote data, enter the URLs in the URLs that remote data columns can be fetched from text box. If you add multiple values, separate them by a new line.

Advanced site settings

You can confgure advanced settings by adding them to the Advanced Site Settings text box.

Autologin

Users with administration privileges can provide unauthenticated access for a user through automatic login.

In Cloudera Machine Learning (CML) and Cloudera Data Science Warehouse (CDSW), authentication for applications is enforced on all ports by default. If needed, an Admin user can allow users to create public applications that can be accessed by unauthenticated users. This is necessary if you do not want users to have to log into CML or CDSW. For information on how to enable unauthenticated access in CML/CDSW, see Public Applications in Securing Applications.

To configure autologin for a user in CDV, add the desired login settings in the Advanced Site Settings text box in key = value format:

AUTOLOGIN_ENABLED = True
AUTOLOGIN_USERNAME = "username"
AUTOLOGIN_PASSWORD = "password"

Concurrency

Add the desired concurrency settings in the Advanced Site Settings text box in key = value format with the following options available:


`DATACONNECTION_CONCURRENCY_DEFAULT`	The default number of concurrent requests per data connections.
`DATACONNECTION_CONCURRENCY_MAX`	The maximum number of concurrent requests per data connections.
`DATACONNECTION_CONCURRENCY_USER_DEFAULT`	The default number of concurrent requests per user.
`DATACONNECTION_CONCURRENCY_USER_MAX`	The default number of maximum concurrent requests per user.

Data extracts

To configure data extracts, add the desired settings in the Advanced Site Settings text box in key = value format. The following options are available:

Prefix for target table names

You can define a prefix for table names. The default value is cdv_.

DATA_EXTRACTS_TARGET_TABLENAME_PREFIX = "cdv_"

Maximum number of rows that can be inserted into a data connection by CDV using data extracts or CSV upload

You can set a system wide maximum value for the maximum number of rows for upload/import all connections.

UPLOAD_MAXROWS_MAX = 1000000000

You can set the default value for the maximum number of rows for upload/import for all connections. You can change the default on each connection in the Edit connection modal. Its value can be only between 0 and UPLOAD_MAXROWS_MAX.

UPLOAD_MAXROWS_DEFAULT = 1000000

Number of rows inserted at a time through data import and data extract inserts

IMPORT_BATCH_INSERT = 1000

Notifications

You can change how long read notifications are kept in the Notifications Center. Add the desired settings in the Advanced Site Settings text box using the BULK_REMOVE_READ_NOTIFICATION_INTERVAL flag.

Size limit for static asset upload

You can configure the size limit for uploading static assets. Add the desired settings in the Advanced Site Settings text box using the DATA_UPLOAD_MAX_MEMORY_SIZE flag.
