Ecto.QueryError on get_by using MultiLevel/DistCache

[bglusman]

I'm experimenting with a Nebulex Repo cache for ecto for some common, rarely changing structs, and I thought a MultiLevel cache was a good fit, with a local and a DistCache on kubernetes... it seems to work fine for the simplest use case, with RepoCache.get working fine, locally or on kubernetes, and RepoCache.get_by works fine locally with jsut LocalCache as the adapter, but when calling a get_by with the same MultiLevel/DistCache adapter, I get the QueryError:

deps/ecto/lib/ecto/repo/queryable.ex:353: keyword lists can only be interpolated at the top level of where, having, distinct, order_by, update or a join's on in query:

from f in MyApp.Module
  where: f.id == ^[user_id: 5, resource_id: 280],
  select: f

Didn't expect the Ecto part would behave differently with different adapters, but curious for thoughts?
