I have billions of keys of type string and values of type HashValueList. I am using BadgerDB to store key-value pairs. In my use case length of HashValueListmight be in millions. I have to Encode key and value in []byte before inserting into BadgerDB; for that, I am using the encoding/gob package. So, whenever I need value, I have to decode them again. When I get HashValueList, I have to work on HashValue in linear time.

Is there any better way to structure HashValue and HashValueList to get high read throughput from DB? And also, what is the best values Options of BadgerDB for my use case.

type HashValue struct {
    Row_id  string
    Address string
}

type HashValueList []HashValue
