Marcel Reutegger commented on OAK-8029:
---------------------------------------
Added two new metrics:
- {{DOCUMENT_NS_MERGE_CHANGES_RATE}}: this meter tracks the number of merged
changes.
- {{DOCUMENT_NS_MERGE_SUCCESS_NORMALIZED_TIME}}: this timer records the
normalized time it took to perform a merge. Normalization is done by dividing
the absolute merge time by the number of merged changes.
Implemented in trunk: http://svn.apache.org/r1853131

> The current merge metrics lack insight how big a merge was. This improvement
> is about adding a metric that tracks the number of changes written by a
> merge. In addition there should be a metric that puts the merge time into
> relation of the number of changes. Only the absolute time of a merge, as
> available right now, is not a good indicator whether performance of those
> operations are OK.
