Setting concurrency for a data connection

You can improve resource management in Cloudera Data Visualization by restricting the number of simultaneous connections on specific datasets.

For information on creating or editing data connections, see Creating a data connection in Cloudera Data Visualization and Editing a data connection.

On the main navigation bar, click DATA.

The Data view appears, open on the Datasets tab.
In the side bar, click to the right of the connection you want to change.

The Edit Data Connection modal appears.
Click the Data tab.
In the Concurrency field, provide a number to set the maximum limit for simultaneous requests.
note
The default maximum concurrency setting per connection is 100. You can change it to a different value in Site Settings > Advanced Settings. If you change the default value, ensure that the new maximum concurrency aligns with the requirements of your data connection.
```
DATACONNECTION_CONCURRENCY_DEFAULT = 100
DATACONNECTION_CONCURRENCY_MAX = 100
```
In the Concurrency Per User field, provide a number to limit the maximum number of simultaneous requests a user can send.
note
You can use this setting to prevent a single user from blocking access for a connection. The default concurrency setting per user is 5, with a default maximum concurrency setting per user at 100. You can adjust these values in Site Settings > Advanced Settings.
```
DATACONNECTION_CONCURRENCY_USER_DEFAULT = 5
DATACONNECTION_CONCURRENCY_USER_MAX = 100
```
Click SAVE to apply the changes.
