Which benchmark are you running? Could you please provide the db_bench options you're using, if any?

[cnbscience]

I have used bulk random fill for this purpose and had modified the script a little to store 5 billion hashes with key size 10 and value size 20.

std::bad_alloc is raised when malloc fails and that happens when RocksDB is configured to use more memory than your server provides -- http://www.cplusplus.com/reference/new/bad_alloc/

You probably need to change the configuration.
