Ok, finally the problem was that I had my neo.props bad configurated. This is the good configuration:
neostore.nodestore.db.mapped_memory=913M neostore.relationshipstore.db.mapped_memory=11G neostore.propertystore.db.mapped_memory=50M neostore.propertystore.db.strings.mapped_memory=100M neostore.propertystore.db.arrays.mapped_memory=0M Also I changed the type String for a int and the identifier for a long. It made that the database decrease around 10 gb . Now, walking for all the nodes and edges spends 9 hours more or less. Thank you very much!
