py2neo - Neo4j - poor performance -

-

i receive daily full csv file customers. need insert/update neo4j database. using query:

i create indexes on hash field.

merge (xfewyx:customer_bseller {hash:'xyz@hotmail.com'} ) on create set xfewyx.hash = 'xyz@hotmail.com',xfewyx.name = 'xyz ',xfewyx.birthdate = '1975-05-20t00:00:00',xfewyx.id = '1770852',xfewyx.nick = 'clarissa',xfewyx.documentnumber = 'xyz',xfewyx.email = 'clarissajuridica@hotmail.com'  xfewyx merge (whhekx:email {hash:'clarissajuridica@hotmail.com'} ) on create set whhekx.hash = 'clarissajuridica@hotmail.com',whhekx.email = 'clarissajuridica@hotmail.com'  xfewyx,whhekx merge (jjkont:document {hash:'06845078700'} ) on create set jjkont.document = 'xyz',jjkont.hash = '06845078700'  xfewyx,whhekx,jjkont merge (merucb:phone {hash:'nonenone'} ) on create set merucb.areacode = 'none',merucb.hash = 'nonenone',merucb.number = 'none'  xfewyx,whhekx,jjkont,merucb merge (boorbt:phone {hash:'xyz'} ) on create set boorbt.areacode = '21',boorbt.hash = 'xyz',boorbt.number = 'xyz'  xfewyx,whhekx,jjkont,merucb,boorbt merge (xblznf:phone {hash:'xyz'} ) on create set xblznf.areacode = '21',xblznf.hash = 'xyz',xblznf.number = 'xyz'  xfewyx,whhekx,jjkont,merucb,boorbt,xblznf merge (xfewyx)-[:registered_with {optin:'false'}]->(whhekx) merge (xfewyx)-[:document]->(jjkont) merge (xfewyx)-[:commercial_phone]->(merucb) merge (xfewyx)-[:phone]->(xblznf) merge (xfewyx)-[:cell_phone]->(boorbt)

does have approach how execute query?

i try using profile command. might put limit on load csv (i assume you're using load csv) testing.

i check out article:

http://www.markhneedham.com/blog/2014/10/23/neo4j-cypher-avoiding-the-eager/

some of has been fixed in recent versions of neo4j, have awful lot of merges there, stand split of , process csv file more once.
