Options

Name of database. Default: graph.db

Configuration file to supply additional configuration in.

Import a collection of CSV files or a pre-3.0 installation. Default: csv

The location of the pre-3.0 database (e.g. <neo4j-root>/data/graph.db).

File in which to store the report of the csv-import. Default: import.report

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. Files can also be specified using regular expressions. For an example, see Using regular expressions for specifying multiple input files.

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. Files can also be specified using regular expressions. For an example, see Using regular expressions for specifying multiple input files.

Each node must provide a unique ID in order to be used for creating relationships during the import. Possible values are: STRING: arbitrary strings for identifying nodes, INTEGER: arbitrary integer values for identifying nodes, ACTUAL: (advanced) actual node ids. Default: STRING

Character set that input data is encoded in. Default: UTF-8

If unspecified columns should be ignored during the import. Default: false

If duplicate nodes should be ignored during the import. Default: false

If relationships referring to missing nodes should be ignored during the import. Default: false

Whether or not fields from input source can span multiple lines, i.e. contain newline characters. Setting --multiline-fields=true can severely degrade performance of the importer. Therefore, use it with care, especially with large imports. Default: false

Delimiter character between values in CSV data. Unicode character encoding can be used if prepended by \. For example, \44 is equivalent to ,. Default: ,

Delimiter character between array elements within a value in CSV data. Unicode character encoding can be used if prepended by \. For example, \59 is equivalent to ;. Default: ;

Character to treat as quotation character for values in CSV data. Quotes can be escaped by doubling them, for example "" would be interpreted as a literal ". You cannot escape using \. Default: "

Maximum memory that neo4j-admin can use for various data structures and caching to improve performance. Values can be plain numbers such as 10000000 or e.g. 20G for 20 gigabyte. It can also be specified as a percentage of the available memory, e.g. 70%. Default: 90%

File containing all arguments, used as an alternative to supplying all arguments on the command line directly. Each argument can be on a separate line, or multiple arguments per line and separated by space. Arguments containing spaces must be quoted. If this argument is used, no additional arguments are supported.

Ignore environment-based heuristics, and specify whether the target storage subsystem can support parallel IO with high throughput. Typically this is true for SSDs, large raid arrays and network-attached storage.
