We are using talaria -> badgerDB -> ristretto cache(dep relationship) and as the mmap issue happened on ristretto, we have to fork badgerDB and ristretto.

After forking, to make sure the dependency works well, we use go module replace like this:
replace github.com/dgraph-io/badger/v3 v3.2103.1 => github.com/atlas-comstock/badger/v3 v3.2103.1-with-arm-fix

At last, I found that the ristretto still use the original version even though I had replaced it in my github.com/atlas-comstock/badger/v3 v3.2103.1-with-arm-fix version.
Therefore, I have to replace them both on talaria:

replace github.com/dgraph-io/badger/v3 v3.2103.1 => github.com/atlas-comstock/badger/v3 v3.2103.1-with-arm-fix

replace github.com/dgraph-io/ristretto v0.1.0 => github.com/atlas-comstock/ristretto v0.2.0
