apoc.load.arrow.stream

In APOC 2025.06 this procedure was migrated to the unsupported APOC Extended library. This means that if you are using APOC 2025.06 or later, the procedure is not available in Cypher 25 but can still be used with Cypher 5. For more information, see APOC and Cypher versions.

Usage Examples

Given an Arrow byte[] contains people and their properties:

test.arrow

name,age,beverage
Selma,9,Soda
Rana,12,Tea,Milk
Selina,19,Cola

We’ll provide a full roundtrip example where we use the apoc.export.arrow.stream.all in order to generate the arrow byte[]

CALL apoc.export.arrow.stream.all() YIELD value AS byteArray
CALL apoc.load.arrow.stream(byteArray) YIELD value
RETURN value

Results
value
{name: "Selma", age: "9", beverage: "Soda"}
{name: "Rana", age: "12", beverage: "Tea;Milk"}
{name: "Selina", age: "19", beverage: "Cola"}
