Purpose


The External Change Log (ECL) provides an alternate view of the replication change log.

The ECL is based on the LDAP changelog draft (https://tools.ietf.org/html/draft-good-ldap-changelog-04) but does not strictly support this change log.
The LDAP change log draft uses an integer as the key to browse the change log whereas the ECL uses a cookie.


The following document explains how to use the External Change Log (ECL).
