Package org.opends.server.replication.server.changelog.api

package org.opends.server.replication.server.changelog.api

This package contains the API for the changelog database. The changelog contains:

• a changelog of all the changes that happened on each server in the replication domain / suffix,
• a changelog as defined by draft-good-ldap-changelog,
• a state database containing specific information about each replica id in the suffix, and in particular the generationId for each server.

The changelog must be purged at regular intervals to ensure it does not consume too much space on disk.
