Alex Parvulescu commented on OAK-4873:
--------------------------------------

I think we can use the estimation check as a way to reduce the frequency of 
compactions. if someone needs to test anything they are free to change the 
settings, otherwise running gc too often should be a cheap noop and estimation 
can provide this protection.

> Avoid running GC too frequently

> As {{RevisionGCMBean.startRevisionGC()}} can be used to manually invoke a gc 
> cycle, there is the danger of running into a {{SNFE}} when gc is run multiple 
> times in quick succession (due to the retention time being based on number of 
> generations). We should come up with a mechanism to prevent this scenario.
