Is Execution Data Pruning Enabled by Default, or Does It Require Manual Activation?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
I'm trying to figure out whether execution data pruning is enabled by default or if I need to set it up manually using environment variables.
Any clarification on how this feature is configured by default would be greatly appreciated.

By default, execution data pruning is enabled. The environment variable controlling this is EXECUTIONS_DATA_PRUNE, which defaults to true. This means that n8n will automatically delete finished executions as per the default settings—specifically, any execution older than 336 hours (14 days) will be pruned if no custom value is provided for EXECUTIONS_DATA_MAX_AGE.
If you want to adjust the pruning behavior (for instance, change the maximum age or limit the number of executions stored), you can override these defaults by setting the corresponding environment variables. For example, to change the retention period, you could set:
SHexport EXECUTIONS_DATA_MAX_AGE=168 # Retain executions for 168 hours (7 days) instead of the default 336 hours
In summary, there's no need to manually enable data pruning—it’s already active unless you disable it or customize the settings.
