Full compaction corresponds to the compaction phase in AEM 6.3. Since full compaction affects the whole repository it requires a considerable amount of system resources and time to complete. The subsequent cleanup phase can thus remove the maximum amount of garbage across the repository.

The full compaction mode rewrites all the segments and tar files in the whole repository.

Full And Tail Compaction ModesĪEM 6.5 introduces two new modes for the compaction phase of the Online Revision Cleanup process:

During the subsequent runs, the repository will temporarily grow while the new generation is created and then stabilize back to the size it had after the first run, as the online revision cleanup process reclaims the previous generation.Īlso, keep in mind that depending on the type and number of commits, each generation can vary in size compared to the previous one, so the final size can vary from one run to the other.ĭue to this fact, it is recommended to size the disk at least two or three times larger than the initially estimated repository size.

This happens because there are now two generations that are kept on disk.

After the first online revision cleanup run the repository will double in size.

So, when you run online revision cleanup after offline revision cleanup the following happens: There is a difference however between the two types of revision cleanup: offline revision cleanup keeps one generation while online revision cleanup keeps two generations. This means that each time you run revision cleanup a new generation is created and kept on the disk. The revision cleanup process reclaims old revisions by generations.

During the compaction phase segments and tar files are rewritten leaving out any unused content.

Estimation determines whether to run the next phase (compaction) or not based on how much garbage might be collected. The revision cleanup process consists of three phases: estimation, compaction and clean up.
