----------------------------------
Summary: DocumentNodeStore should provide option to set initial
cache size as percentage of MAX VM size
Key: OAK-2779
URL: https://issues.apache.org/jira/browse/OAK-2779
Project: Jackrabbit Oak
Issue Type: Improvement
Components: mongomk
Affects Versions: 1.2
Reporter: Will McGauley
Fix For: 1.2.1
Currently the DocumentNodeStore provides a way to configure various cache
parameters, including cache size and distribution of that size to various
caches. The distribution of caches is done as a % of the total cache size,
which is very helpful, but the overall cache size can only be set as a literal
value.
It would be helpful to achieve a good default value based on the available VM
memory as a %, instead of a literal value. By doing this the cache size would
not need to be set by each customer, and a better initial experience would be
achieved.
I suggest that 25% of the max VM size would be a good starting point.
