Indexed DB - N-Dimensional Selection

The problem

We have an index with keys of the form:

[ dim1, dim2, dim3, ... ]

e.g. created with:

gaearon

import { combineReducers } from 'redux';
import users from './reducers/users';
import posts from './reducers/posts';

export default function createReducer(asyncReducers) {
  return combineReducers({
    users,
    posts,
    ...asyncReducers
  });
