I have a Neo4j 3.5.3 installation on my Ubuntu laptop (which is Intel i5, 4 GB RAM, SSD disk) and I'm trying to import a moderate-sized dataset from CSV files into the graph.
Here is the full Cypher script I use:
MATCH (x :Shop ) DETACH DELETE x RETURN count(*) AS DeletedShops;
MATCH (x :Postal ) DETACH DELETE x RETURN count(*) AS DeletedPostal;
MATCH (x :City ) DETACH DELETE x RETURN count(*) AS DeletedCities;
MATCH (x :Locator ) DETACH DELETE x RETURN count(*) AS DeletedLocators;
MATCH (x :Brand ) DETACH DELETE x RETURN count(*) AS DeletedBrands;
MATCH (x :Industry ) DETACH DELETE x RETURN count(*) AS DeletedIndustries;
USING PERIODIC COMMIT 10000
LOAD CSV WITH HEADERS FROM 'file:///accounts.csv.gz' AS csv
//locatorschemaname,accountname,clientname,clientindustry,accountindustry,locationcount
MERGE (b:Brand {name: csv.clientname})
FOREACH(n IN (CASE WHEN csv.clientindustry IS NOT NULL AND NOT toLower(csv.clientindustry) IN ['na','unknown','other'] THEN ELSE [] END) |
MERGE (i:Industry {name: csv.clientindustry})
MERGE (b)-[:INDUSTRY]->(i)
)
FOREACH(n IN (CASE WHEN csv.accountindustry IS NOT NULL AND NOT toLower(csv.accountindustry) IN ['na','unknown','other'] THEN ELSE [] END) |
MERGE (i2:Industry {name: csv.accountindustry})
MERGE (b)-[:INDUSTRY]->(i2)
)
// Brand.shops = max(locator.shops)
FOREACH(n IN (CASE WHEN csv.locatorschemaname IS NOT NULL AND csv.locatorschemaname=csv.accountname THEN ELSE [] END) |
MERGE (l:Locator {name: csv.locatorschemaname, shops: toInt(csv.locationcount)})
MERGE (l)-[:BRAND]->(b)
SET b.shops = CASE
WHEN b.shops IS NULL OR b.shops (i:Industry)
WITH i.name AS iname, sum(b.shops) AS isum
MATCH (ii:Industry {name: iname})
SET ii.shops = isum;
// NOTE: This is done in multiple-pass mode, to avoid performance issues with NEo4j CE 3.4.7 on ubuntu
// NOTE: We do not use WITH HEADERS as it adds a 40%+ overhead
// PASS 1. Shops
USING PERIODIC COMMIT 10000
LOAD CSV FROM 'file:///locations.csv.gz' AS csv
// schemaname,clientkey,name,address1,address2,city,region,country,postalcode,latitude,longitude
// find existing locator node
MATCH (l :Locator {name: csv})
CREATE (s:Shop {
locatorname: csv,
clientkey: csv,
latitude: toFloat(csv),
longitude: toFloat(csv)
})
CREATE (s)-[:LOCATOR]->(l);
CREATE INDEX ON :Shop (locatorname, clientkey);
MATCH (:Shop) RETURN count(*) AS ShopsCreated;
// PASS 2. cities
USING PERIODIC COMMIT 10000
LOAD CSV FROM 'file:///locations.csv.gz' AS csv
WITH csv WHERE csv IS NOT NULL
MATCH (s:Shop {locatorname: csv, clientkey: csv})
MERGE (city :City {name: csv, country: csv}) ON CREATE SET city.region = csv
MERGE (s)-[:CITY]->(city);
MATCH (:City) RETURN count(*) AS CitiesCreated;
// PASS 3. postal codes
USING PERIODIC COMMIT 10000
LOAD CSV FROM 'file:///locations.csv.gz' AS csv
WITH csv WHERE csv IS NOT NULL
MATCH (s:Shop {locatorname: csv, clientkey: csv})
MERGE (postal :Postal {name: csv, country: csv}) ON CREATE SET postal.region = csv
MERGE (s)-[:POSTAL]->(postal);
MATCH (:Postal) RETURN count(*) AS PostalcodesCreated;
CREATE CONSTRAINT ON (i:Industry) ASSERT i.name IS UNIQUE;
CREATE CONSTRAINT ON (b:Brand) ASSERT b.name IS UNIQUE;
CREATE CONSTRAINT ON (l:Locator) ASSERT l.name IS UNIQUE;
The problem is, the scripts makes it fairly quickly to the end of "PASS 1", and then it apparently hangs on "PASS 2". The server process is churning CPU and nothing visible happens. This lasts at least 120 minutes and does not look like it's going to finish any time soon.
I use default settings for heap size etc. But on-disk size of the whole dataset (checked in /var/lib/neo4j/data) is ~~ 500 MB. So this machine should handle it.
Here is the output so far:
DeletedShops
0
DeletedPostal
0
DeletedCities
0
DeletedLocators
0
DeletedBrands
0
DeletedIndustries
0
IndustriesCreated
18
BrandsCreated
1326
LocatorsCreated
2092
ShopsCreated
937488

And here is some

How can I rewrite the script to achieve same thing faster?
What can I do to diagnose the bottleneck?
Is this at all doable using limited (1-2 GB) java heap size - and why not?
**Update**: here is result of a short strace -v -tt -f -s 100 -p :
