Problem
It seems some parameter settings have been changed in the past. As a result, some tests (at least one) lose the ability to test what they want to test.
For
BenchmarkDbGrowth
, current default value ofValueThreshold
makes no vlog will be created and current default value ofMemTableSize
makes no memtable will be flushed which means no compaction and thus no vlog gc will be performed.Solution
Setting
ValueThreshold
be 1024 andMemTableSize
be 1MB in this case seems to be fine.
