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.

Open the Edit Data Connection modal.
For more information, see Editing a data connection.
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.
