org.camunda.bpm.engine.impl.history.HistoryLevel
The history level controls what kind of data is logged to the history database. More formally, it controls which history events are produced by the {@link HistoryEventProducer}.

Built-in history levels: The process engine provides a set of built-in history levels as default configuration. The built-in history levels are:
- {@link #HISTORY_LEVEL_NONE}
- {@link #HISTORY_LEVEL_ACTIVITY}
- {@link #HISTORY_LEVEL_AUDIT}
- {@link #HISTORY_LEVEL_FULL}
This class provides singleton instances of these history levels as constants.

Custom history levels:In order to implement a custom history level, the following steps are necessary:
- Provide a custom implementation of this interface. Note: Make sure you choose unique values for {@link #getName()} and {@link #getId()}
- Add an instance of the custom implementation through {@link ProcessEngineConfigurationImpl#setCustomHistoryLevels(java.util.List)}
- use the name of your history level (as returned by {@link #getName()} as value for{@link ProcessEngineConfiguration#setHistory(String)}
