The --skip-duplicate-nodes flag will skip import of nodes with the same ID instead of aborting the import.

It seems you have trailing spaces or tabs in your file? Please remove them.

If it is all the same rel-type you can also provide it

QUESTION

how to import multiple relationships files (file groups) into neo4j with neo4j-import?

Asked 2017-Aug-20 at 05:43

this example in the neo4j docs shows multiple groups of nodes files, but only one group of relationships files.

neo4j_home$ ./bin/neo4j-import --into path_to_target_directory --nodes "movies4-header.csv,movies4-part1.csv,movies4-part2.csv" --nodes "actors4-header.csv,actors4-part1.csv,actors4-part2.csv" --relationships "roles4-header.csv,roles4-part1.csv,roles4-part2.csv"

what is the syntax to import multiple relationships files into neo4j with neo4j-import?

I can imagine extending the example to also have a DIRECTED_IN relationship type, which would be described in a file called directed-in4.csv

then, I could imagine that the call to neo4j-import would look like this:

with the additional --relationships directed-in4.csv tacked on at the end. Is this the correct approach?

...

ANSWER

Answered 2017-Aug-20 at 05:43

it appears that specifying multiple relationships does work like this:

neo4j_home$ ./bin/neo4j-import --into path_to_target_directory --nodes "movies4-header.csv,movies4-part1.csv,movies4-part2.csv" --nodes "actors4-header.csv,actors4-part1.csv,actors4-part2.csv" --relationships "roles4-header.csv,roles4-part1.csv,roles4-part2.csv" --relationships directed-in4.csv

with the additional --relationships argument

ANSWER

Answered 2017-Jun-01 at 17:58

[EDITED]

If you want your relationships to have dynamically assigned types, then you need to change your Cypher code to make use of line[2] to specify the relationship type (e.g., via the APOC procedure apoc.create.relationship). It is currently always using test as the type.
If, instead, you actually wanted all the relationships imported by neo4j-import to have the same test type, then you need to use the right syntax.

Try removing ",:TYPE" from rheader, and use this import command line ( --relationships has been changed to --relationships:test):

QUESTION

Label counts are often wrong

Asked 2017-Feb-21 at 17:16

I'm regularly building and deleting whole datasets using the batch importer (neo4j-import), but I often find that the cached counts on labels are wrong. For example, MATCH (n:Label) RETURN COUNT(n) returns 560, but MATCH (n:Label) WHERE EXISTS(n.attribute_all_nodes_have) RETURN COUNT(n) returns > 750,000 (which is the correct number).

This is especially problematic because it makes certain queries very slow. For example, MATCH (a:Label1)-[r]-(b:Label2) WITH r LIMIT 5 DELETE r took 14 seconds.

Deleting and rebuilding the dataset sometimes fixes this, but that takes a long time (10s of millions of nodes). Is there a way to fix the label counts in place?

FYI I'm on Neo4j 3.1.0 on MacOS Sierra 10.12.3.

ANSWER

Answered 2017-Feb-21 at 17:16

The counts after an import should be correct, however if they are not there's always the possibility to shut down db, delete the counts store neostore.counts.db.* and start anew. The counts will be rebuilt, however using the same functionality which the import tool uses to build the counts.

May be class mixup of different versions and precedence of jar could be the reason.

Embedded Tomcat version: 8.5.11

Try removing the embedded tomcat jars from the project while running in a standalone container.
