How can I query in huge map/list with lazy ?

Will eclipsestore load every object occured when using Stream::filter ? How to deal with clean up when mass of objects was loaded in Stream::filter ?

A Lazy-Referenced object will be loaded whenever Lazy.get() is called. It does not matter if this done while using Java Streams or any other api. When a lazy is loaded it will load everything, not only the lazy referenced object itself, but also the whole object graph starting with the lazy object as it’s root.
Lazy loaded data can be unloaded in several ways:

• Eclipse store will occasionally unload lazy referenced.
• Explicitly unload a Lazy by calling Lazy.clear()
• Utilize the static LazyReferenceManager to get access to all lazy references.

Please see Clearing Lazy References for more details.

Please also note that lazy loaded objects must be collected by the Java Garbage Collector to actually release memory.
