Neo4j Transfer

README 文档

README

Directly transfer nodes and relations between Neo4j servers or backup/restore entire databases to/from files.

Building

This tool may be built as a stand-alone phar file by using the following commands:

git clone https://github.com/liutec/neo4jtransfer.git
cd neo4jtransfer
composer install
./bin/build
./neo4jtransfer.phar help

Commands and arguments

The following commands are available:

The dump command

Dump all nodes and relations from a Neo4j database into a cypher file.

Dump command example

The following command will dump all nodes and relations from neo4j1-prod into a file. (eg. dump-neo4j1-prod-20160615-233212.cypher)

./neo4jtransfer.phar dump --output=default --source-host=neo4j1-prod

Dump command arguments

Argument	Default value	Description
`--source-host`	`localhost`	Neo4j source server hostname.
`--source-port`	`7474`	Neo4j source server port.
`--source-user`	`neo4j`	Neo4j source server username.
`--source-password`	`neo4j`	Neo4j source server password.
`--output`	`STDOUT`	Cypher output filename. If unspecified, will use STDOUT. Set to `default` to use `dump-[source-host]-[yyyyMMdd]-[hhmmss].cypher`
`--read-batch-size`	`300`	The number of nodes and relations to read at once.
`--node-batch-size`	`100`	The number of nodes to write as part of a single cypher query or batch.
`--relation-batch-size`	`150`	The number of relations to write as part of a single cypher query or batch.
`--ignore-relation-properties`	`none`	Comma separated values of properties to be ignored for relations. . (eg. creationDate,modificationDate)
`--preserve-ids`	`none`	Comma separated list of label attributes to treat as Node IDs. (eg. Job.ownerId,Action.userId)
`--clean`	`true`	Set to `false` not to clean target database before importing. By default all nodes and relations will be removed.
`--transactional`	`false`	Set to `true` to wrap all cyphers in a transaction. Non-transactional by default.
`--import-label`	`_ilb`	The name of the label set on imported nodes to create a temporary index with which to quicker identify nodes when transferring relations. This label and the index on it will be removed after the import.
`--import-id-key`	`_iid`	The name of the key used to hold the node IDs as imported. This attribute and the index on it will be removed after the import.

The import command

Run cypher queries from a file.

Import command example

The following command will look for the latest dump corresponding to the neo4j1-prod host (eg. dump-neo4j1-prod-20160615-233212.cypher) and execute the cypher queries within onto the Neo4j database on localhost.

./neo4jtransfer.phar import --input=last:neo4j1-prod

Import command arguments

Argument	Default value	Description
`--input`	`STDIN`	Cypher input filename. If unspecified, will use STDIN. Set to `last:[hostname]` to use `dump-[hostname]-[yyyyMMdd]-[hhmmss].cypher` with the latest timestamp.
`--target-host`	`localhost`	Neo4j target server hostname.
`--target-port`	`7474`	Neo4j target server port.
`--target-user`	`neo4j`	Neo4j target server username.
`--target-password`	`neo4j`	Neo4j target server password.

The direct transfer command

Transfer nodes and relations from one Neo4j database into another without an intermediary dump file.

Direct transfer command example

The following command will transfer all nodes and relations from neo4j1-prod into app1-dev within a single transaction.

./neo4jtransfer.phar direct --source-host=neo4j1-prod --target-host=app1-dev --transactional

Direct transfer command arguments

Argument	Default value	Description
`--source-host`	`localhost`	Neo4j source server hostname.
`--source-port`	`7474`	Neo4j source server port.
`--source-user`	`neo4j`	Neo4j source server username.
`--source-password`	`neo4j`	Neo4j source server password.
`--target-host`	`localhost`	Neo4j target server hostname.
`--target-port`	`7474`	Neo4j target server port.
`--target-user`	`neo4j`	Neo4j target server username.
`--target-password`	`neo4j`	Neo4j target server password.
`--read-batch-size`	`300`	The number of nodes and relations to read at once.

`--transactional`	`false`	Set to `true` to wrap all cyphers in a transaction. Non-transactional by default.

The transfer command

Transfer nodes and relations from one Neo4j database into another and save all cypher queries to a dump file.

Transfer command example

The following command will transfer all nodes and relations from neo4j1-prod into app1-dev within a single transaction and create a dump file for backup. (eg. dump-neo4j1-prod-20160615-233212.cypher)
