It is so important to test before your graph used in a production environment
so I test badger with java-leveldb . with the same logic , level take ten percents of disk compare with badger
why this happen? leveldb has data compression?
during inserting data ,badger db use up my memory while java-level db only use 30% of memory , is quite difficult to understand ,do you think so ?
I have check for badger ,it is obvious memory table and immutable memory table is not for reason.
