Dashboard Size Issue.

[Vidyaranya-Gavai-TTPL]

Hi Everyone!

I got this error while adding a new chart on a dashboard:
Your dashboard is too large. Please reduce its size before saving it.

Is there a config to increase space allocated to each dashboard, or any way around it?

Superset enforces a dashboard size limit to prevent performance and storage issues. The error appears when the serialized dashboard layout data exceeds the configured limit. By default, this limit is set to 65,535 characters, but you can increase it by setting the SUPERSET_DASHBOARD_POSITION_DATA_LIMIT value in your Superset configuration.

To do this, add the following line to your superset_config.py file (or your custom config file if using the SUPERSET_CONFIG_PATH environment variable):

SUPERSET_DASHBOARD_POSITION_DATA_LIMIT = 120000  # or any higher value you need

Then restart Superset for the change to take effect. This will allow you to save larger dashboards. The value is passed from backend to frontend and will be enforced in the UI as well source.

Keep in mind that increasing this limit may impact performance or stability, especially for very large dashboards. If you run into issues, consider splitting your dashboard into smaller ones.

Let me know if you need more details on where to place the config or how to reload Superset!

@dosu what is '120000' in 'SUPERSET_DASHBOARD_POSITION_DATA_LIMIT = 120000'?

[dosubot[bot]]

The value 120000 in SUPERSET_DASHBOARD_POSITION_DATA_LIMIT = 120000 sets the maximum number of characters allowed for the serialized dashboard layout data. If your dashboard's layout data exceeds this number of characters, Superset will block you from saving it and show the "dashboard is too large" error. Raising this limit lets you save larger dashboards, but very large dashboards may impact performance or stability. You can set this value in your superset_config.py file if you need more space.
