apoc.export.arrow.stream.query

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.

Usage Examples

Let’s suppose we have this data set:

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 {name: 'John', age:12}),(d:Another {foo: 'bar'})

With this query:

CALL apoc.export.arrow.stream.query('MATCH (n:User) RETURN count(n) as count, n.name as name')
YIELD value RETURN value

We’ll have a table with the following columns:

count
name
