-------------------------------
Labels: performance resilience (was: )
> 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
> Labels: performance, resilience
> Fix For: 1.3.5
>
>
> 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.
