At the moment, at migrate/update time, there is a merge of the old and new properties helm by the instance. However, this merge of properties does not take account of nested maps that need to be recursively merged.
Solution 1
For any "property" of the new Map, recursive update will be apply only if in both new and old map, the type of the value "map.get(property)" are Map.
Type of oldMap.get(property) | Type of newMap.get(property) | Operation |
|---|---|---|
| int/string/boolean/list | Map | update |
| Map | int/string/boolean/list | update |
| int/string/boolean/list | int/string/boolean/list | update |
| Map | Map | recursive update |
| not present | int/string/boolean/list/map | no update |
| int/string/boolean/list/map | not present | insert |
| null | int/string/boolean/list/map | delete |
