Hi, There is currently no good documentation or explanation on Nioneo. I would suggest you have a look at the code in org.neo4j.impl.nioneo.store.
We used fixed size records to store nodes and relationships (see NodeStore and RelationshipStore). Relationships are stored in a "interleaved double linked list". Each store may have memory mapped regions (depending on configuration and request patterns) with a fall back on direct buffers. The store files are only flushed when logical log needs to rotate making it easier for the OS and file system in place to perform disk I/O optimizations. -Johan On Sun, Mar 29, 2009 at 12:00 PM, afterstep 13 <[email protected]> wrote: > I am trying to understand how nioneo stores nodes and relationships on the > disk. > > How does nioneo organize nodes and relationship in these files.
