qhana_plugin_runner.db.models.mutable_json module

This module provides a helper class MutableJSON that can be used as a column in SQL Alchemy. SQL Alchemy’s built-in JSON type is immutable and hence inflexible for usage as a key-value storage. MutableJSON supports all primitive types in JSON (str, float, int and bool) as well nested dicts and lists with change tracking.
