neo4j-admin使用笔记

neo4j-admin import 虽然在以后的版本里会把 neo4j-import 替掉，但是我感觉neo4j-import好用，比neo4j-admin import多一些参数

usage: neo4j-admin import [--mode=csv] [--database=<name>]
[--additional-config=<config-file-path>]

[--input-encoding=<character-set>]
usage: neo4j-admin import --mode=database [--database=<name>]
[--additional-config=<config-file-path>]
[--from=<source-directory>]
Import a collection of CSV files with --mode=csv (default), or a database from a
pre-3.0 installation with --mode=database.
options:
--database=<name>
Name of database. [default:graph.db]
--additional-config=<config-file-path>

--report-file=<filename>
File in which to store the report of the csv-import.
[default:import.report]
--nodes[:Label1:Label2]=<"file1,file2,...">
Node CSV header and data. Multiple files will be logically seen as one big
file from the perspective of the importer. The first line must contain the
header. Multiple data sources like these can be specified in one import,
where each data source has its own header. Note that file groups must be
enclosed in quotation marks. [default:]
--relationships[:RELATIONSHIP_TYPE]=<"file1,file2,...">
Relationship CSV header and data. Multiple files will be logically seen as
one big file from the perspective of the importer. The first line must
contain the header. Multiple data sources like these can be specified in
one import, where each data source has its own header. Note that file
groups must be enclosed in quotation marks. [default:]
--id-type=<STRING|INTEGER|ACTUAL>
Each node must provide a unique id. This is used to find the correct nodes
when creating relationships. Possible values are:
STRING: arbitrary strings for identifying nodes,
INTEGER: arbitrary integer values for identifying nodes,
ACTUAL: (advanced) actual node ids.
For more information on id handling, please see the Neo4j Manual:
https://neo4j.com/docs/operations-manual/current/tools/import/
[default:STRING]
--input-encoding=<character-set>
Character set that input data is encoded in. [default:UTF-8]
