+// The configuration of feature flags is stored in a table in DynamoDB.
+// Each row is identified by a compound primary key consisting of
+// partition key - platform and sort key - feature.
+// A row also contains the configuration, which is a map indexed  by code
+// version with values containing boolean flags for staff and non-staff config.
+// A sample row from the db looks like this:
+// {
+//   "feature": S("FEATURE_1"),
+//   "configuration": M({
+//     "123": M({
+//       "staff": Bool(true),
+//       "non-staff": Bool(false)
+//     })
+//   }),
+//   "platform": S("ANDROID")
+//  }
