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 configure various advanced settings in Cloudera Data Visualization by adding them to the Advanced Site Settings text box.

Autologin

Users with administrative privileges can enable unauthenticated access 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 accessible by unauthenticated users. This is needed if you do not want users 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 following settings in the Advanced Site Settings text box in key = value format:

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

Concurrency

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


`DATACONNECTION_CONCURRENCY_DEFAULT`	Default number of concurrent requests per data connections
`DATACONNECTION_CONCURRENCY_MAX`	Maximum number of concurrent requests per data connections
`DATACONNECTION_CONCURRENCY_USER_DEFAULT`	Default number of concurrent requests per user
`DATACONNECTION_CONCURRENCY_USER_MAX`	Default number of maximum concurrent requests per user

These settings control the number of concurrent requests per data connection and 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

To configure how long read notifications are kept in the Notifications Center, add the BULK_REMOVE_READ_NOTIFICATION_INTERVAL flag in the Advanced Site Settings text box.

Size limit for static asset upload

To configure the size limit for uploading static assets, add the DATA_UPLOAD_MAX_MEMORY_SIZE flag in the Advanced Site Settings text box.

Filter association configuration

To enable Filter Association (FA) based on Manage dataset permission, add the MANAGE_DS_FA = True flag in the Advanced Site Settings text box.
