Replication increases the disk space required for the PingDirectory server.
The Replication Changelog backend keeps changes from all PingDirectory servers for 24 hours by default. After this time period, also known as the purge delay, the backend is trimmed automatically.
In addition, within the
userRoot and other local DN backends, attribute-level changes are recorded for a short period of time in the
ds-sync-hist attribute of the
entry targeted by an LDAP Modify operation. This attribute is used to resolve all conflicts
resulting from LDAP Modify operations automatically.
The disk space impact of replication is dependent on the rate and size of changes in the replication topology and the Replication Changelog purge delay.
