When using Neo4j in the embedded mode (Java API), one can manually set memory map settings using the following API calls (or similar):
GraphDatabaseSettings.nodestore_mapped_memory_size GraphDatabaseSettings.relationshipstore_mapped_memory_size GraphDatabaseSettings.mapped_memory_page_size GraphDatabaseSettings.strings_mapped_memory_size GraphDatabaseSettings.arrays_mapped_memory_size
My question is: Is the mapped memory allocated out of Java heap/extended memory or from the rest of the memory available. I know that for Neo4j server the latter is correct as long as it is run on Linux/Unix machines. But can someone confirm whether the same holds for the embedded version?
On Windows: from the heap
On MacOs/Unix: from the rest of the RAM
Embedded and server behave the same. That config for server is in
