`static java.lang.String`	`FEATURE_ENRICHER_PERSISTENCE_PROPERTY`
`static java.lang.String`	`FEATURE_FEED_PERSISTENCE_PROPERTY`
`static java.lang.String`	`FEATURE_FEED_REGISTRATION_PROPERTY` whether feeds are automatically registered when set on entities, so that they are persisted
`static java.lang.String`	`FEATURE_POLICY_PERSISTENCE_PROPERTY`
`static java.lang.String`	`FEATURE_RENAME_THREADS` Renaming threads can really helps with debugging etc; however it's a massive performance hit (2x)
`static java.lang.String`	`FEATURE_USE_BROOKLYN_LIVE_OBJECTS_DATAGRID_STORAGE` whether to attempt to use `BrooklynStorage` (datagrid) as a backing store for data; note this is not compatible with `FEATURE_DEFAULT_STANDBY_IS_HOT_PROPERTY` which uses a blob/file store and a larger-granularity rebind process than was intended with the datagrid
