Hey @pymnh thanks for opening the issue!

Truth be told I haven't dug into the Badger integration in a looong time. However, I recall that specific architectures require Badger to be run with configuration flags that restrict the memory, disk, addressable bit space.

I think the error you're seeing is a known Badger error (dgraph-io/badger#246) -- it's Badger yelling that it doesn't have enough room to run. Since we generally test in 64 bit environments, we haven't optimized the tests to run in 32 bit environments. If you'd like to post a PR with the changes necessary to run the tests against a 32 bit env, we'll happily merge. I imagine it would just be adding some options here -

nosql/nosql_test.go

Line 344 in 78e6f87

db, err := New("badger", path, WithValueDir(path))

.

Cheers 🍻
