[openldap 2.4]olcdbcheckpoint parameter is not working

To whom it may concern,

Could you confirm if the following understanding is correct?

Regarding the olcDbCheckpoint parameter in openldap-2.4.46-18, it is mentioned in the 2.4 manual but it does not seem to work even when the setting is enabled and tested. Upon investigating the source code, it appears that the parameter is deactivated. Based on these results, it is speculated that it will not work as expected because it is an unimplemented item, Is this hypothesis right?

* 2.4 manual https://www.openldap.org/doc/admin24/slapdconf2.html 5.2.6.3. olcDbCheckpoint: <kbyte> <min>

I am looking forward to your response.

regards
