Issue ID: 9688 Summary: Is EQ index on entryCSN mandatory for replication? Product: OpenLDAP Version: 2.5.7 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: documentation Assignee: bugs@openldap.org Reporter: dpa-openldap@aegee.org Target Milestone: ---
https://www.openldap.org/devel/admin/replication.html says about the EQ index on entryCSN: “On databases which support inequality indexing, setting an eq index on the entryCSN attribute and configuring contextCSN checkpoints will greatly speed up this scanning step.” → The index is recommended, but not mandatory, and not always possible.
man 5 slapo-syncprov / https://www.openldap.org/software/man.cgi?query=slapo-syncprov&apropos=0... says “On databases that support inequality indexing, it is mandatory to set an eq index on the entryCSN attribute when using this overlay.”
Between both documents there is a discrepancy, whether the EQ index is mandatory or not.
