Ahmad, could you also store the properties of the hashtable as properties of the node itself? How many entries are in such a hashtable ?
You might configure the block-size of the string store to a different value to fit your typical hashtable-size better (which would affect the storage of the smaller string properties). (http://wiki.neo4j.org/content/Configuration_Settings#Block_size) For the small string properties, it is perhaps possible to fit them into a short-string? (http://journal.thobe.org/2011/02/better-support-for-short-strings-in.html) Unfortunately your output of "du" only shows directories. What would be most interesting here is a: ls -lh data/graph.db Thanks Michael Am 08.08.2011 um 16:29 schrieb ahmad.bakr: > I am using Neo4j REST API, so whenever i need to store data in Neo4j, i have > to convert it to its JSON representation and send it to Neo4j.
