apoc.export.arrow.stream.all

Procedure

apoc.export.arrow.stream.all(config MAP<STRING, ANY>) - exports the full database as an arrow byte array.

This procedure is not considered safe to run from multiple threads. It is therefore not supported by the parallel runtime (introduced in Neo4j 5.13). For more information, see the Cypher Manual → Parallel runtime.

Signature

apoc.export.arrow.stream.all(config = {} :: MAP) :: (value :: LIST<INTEGER>)

Input parameters

Name Type Default

config

MAP

null

Output parameters

Name Type

value

LIST<INTEGER>

Usage Examples

The procedure expose an Arrow byte[] for each batch of rows with the following structure - <id>: for node id - <labels>: list of labels - <source.id>: source node id (in case of relationship) - <target.id>: target node id (in case of relationship) - <type>: for relationship type - the list of properties of nodes and relationships flattened as table

So for the following query:

CREATE (f:User {name:'Adam',age:42,male:true,kids:['Sam','Anna','Grace'], born:localdatetime('2015185T19:32:24'), place:point({latitude: 13.1, longitude: 33.46789})})-[:KNOWS {since: 1993, bffSince: duration('P5M1.5D')}]->(b:User {name:'Jim',age:42}),(c:User {age:12}),(d:Another {foo: 'bar'})

With this query:

CALL apoc.export.arrow.stream.all()

We’ll have a table with the following columns:

  • <id>

  • <labels>

  • <source.id>

  • <target.id>

  • <type>

  • name

  • age

  • male

  • kids

  • born

  • place

  • since

  • bffSince
