----------------------------------

             Summary: User Guide - compaction-threshold mechanism descriptions 
are wrong
                 Key: GEODE-8533
                 URL: https://issues.apache.org/jira/browse/GEODE-8533
             Project: Geode
          Issue Type: Bug
          Components: docs
    Affects Versions: 1.13.0
            Reporter: Dave Barnes


Zhengzhi Xu reports:

The compaction threshold mechanism is misleading in current document.

CompactionThreshold is percentage of remaining live data in the oplog at which 
an oplog is compactable, while current user document is described as percentage 
of garbage in the oplog like the below:
--compaction-threshold: Percentage of garbage allowed in the file before it is 
eligible for compaction.

The correct description is in the API document:
{code:java}
DiskStoreFactory setCompactionThreshold(int compactionThreshold) Sets the 
threshold at which an oplog will become compactable. Until it reaches this 
threshold the oplog will not be compacted. The threshold is a percentage in the 
range 0..100. When the amount of live data in an oplog becomes less than this 
percentage then when a compaction is done this garbage will be cleaned up 
freeing up disk space. Garbage is created by entry destroys, entry updates, and 
region destroys. Parameters: compactionThreshold - percentage of remaining live 
data in the oplog at which an oplog is compactable{code}
