Admin Import Neo4j 3.x vs 4.x

[adrian_romanik]

I have already searched and tried a lot. It is clear to me that Neo4j in version 4 multiples the databases in a different directory.

By the way, I am using Neo4j Desktop 1.4.3 with Zulu Java 11.

However, the admin import does not seem to create the database, which is empty. Difference between graph.db (V3) and Neo4j (V4) in the newer version is also clear.

Furthermore the program does not know "--mode=csv" anymore(?).

By the way, 5 large csv files are to be imported.

The admin import for Neo4j Desktop Version 4 (doesn't work)

SET dirNeo4jDb=C:\Users\xt35386.Neo4jDesktop\relate-data\dbmss\dbms-548a1c5a-cac2-4c70-919c-f108fe353b06

::***********************************************************************************************************
::Start with batch programm
::***********************************************************************************************************

CALL rmdir "%dirNeo4jDb%\data\databases\neo4j" /s /Q

:: Create new database (nodes and edges):

CALL %dirNeo4jDb%\bin\neo4j-admin import ^
-- mode= csv^
--database = neo4j ^
--delimiter=";" ^
--array-delimiter="|" ^
--id-type=STRING ^
--nodes="%dirNeo4jDb%\import\Knoten_nat.csv"^
--nodes="%dirNeo4jDb%\import\Knoten_jur.csv"^
--nodes="%dirNeo4jDb%\import\Knoten_re.csv"^
--relationships="%dirNeo4jDb%\import\Kanten_1_2.csv" ^
--relationships="%dirNeo4jDb%\import\Kanten_2_1.csv"

The whole admin import looks like this in version 3, which works:

SET dirNeo4jDb=C:\Users\Ulrike.Neo4jDesktop\neo4jDatabases\database-c288f0c8-a632-4675-8355-a1d2a4e0549d\installation-3.5.6\

::***********************************************************************************************************
::Start with batch programm
::***********************************************************************************************************

CALL rmdir "%dirNeo4jDb%\data\databases\graph.db" /s /Q

:: Create new database (nodes and edges):

CALL %dirNeo4jDb%\bin\neo4j-admin import ^
--mode=csv ^
--database=graph.db ^
--delimiter=; ^
--array-delimiter="|" ^
--id-type=STRING ^
--nodes="%dirNeo4jDb%\import\Knoten_nat.csv"^
--nodes="%dirNeo4jDb%\import\Knoten_jur.csv"^
--nodes="%dirNeo4jDb%\import\Knoten_re.csv"^
--relationships="%dirNeo4jDb%\import\Kanten_1_2.csv" ^
--relationships="%dirNeo4jDb%\import\Kanten_2_1.csv"

Thanks a lot!!!

Yes mode=csv is gone

the rest should still mostly work, see here in the docs

Neo4j Graph Database Platform

Import - Operations Manual

This section describes how to perform batch imports of data into Neo4j using the command line tool `neo4j-admin import`.

You should not remove database directories, instead use --force to override

neo4j 4.x has separate directories for databases and transaction logs that you would have both to delete.
