Yes, Michael is correct, you must await the index to be ONLINE in a
separate transaction because the index starts to populate first when
closing the transactions.

Hi,
That definitely sounds worrying and unexpected. If you could make available
code to reproduce this it would be most helpful.

With the traversal framework, the actual work of traversing happens lazily
on every call on hasNext/next on the returned Traverser (in the end
Iterator). You can simply stop pulling more paths after a certain
number of paths have been extracted.

neo4j-import can currently only add new nodes/relationships and add
properties to those new nodes/relationships. It cannot currently update
existing entities.

Max, `.nodes()` does this, gets the `endNode()` of all paths.

Perhaps GC? Sounds like far too many threads and things could potentially
go a lot faster with fewer threads, something like number of cores on the
server or some small multiple of that.
