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.
