GRAPH.CONFIG-SET

Set the value of a FalkorDB configuration parameter.

Values set using GRAPH.CONFIG SET are not persisted after server restart.

FalkorDB configuration parameters are detailed here.

Note: As detailed in the link above, not all FalkorDB configuration parameters can be set at run-time.

Multiple parameters can be set in a single command:

GRAPH.CONFIG SET key1 val1 key2 val2 ...

Frequently Asked Questions 4

Are configuration changes persisted after a server restart?

No. Values set using GRAPH.CONFIG SET are not persisted after server restart. To make changes permanent, update the server configuration file or use startup arguments.

Can all configuration parameters be changed at runtime?

No. Some parameters like THREAD_COUNT can only be set at server startup. Attempting to change them at runtime will return an error: ‘This configuration parameter cannot be set at run-time’.

Can I set multiple configuration parameters in a single command?

Yes. You can set multiple parameters at once: GRAPH.CONFIG SET key1 val1 key2 val2 ...

What happens if I set an invalid value?

The command will return an error and the configuration parameter will retain its previous value. No partial changes are applied.
