Given the following CSV file:

<s3 path>
colA:byte,colB:short,colC:int,colD:long,colE:float,colF:double,colG:string
-128,-32768,-2147483648,-9223372036854775808,1.23456,1.23457,first
127,32767,2147483647,9223372036854775807,nan,nan,second
0,0,0,0,-inf,-inf,third
0,0,0,0,inf,inf,fourth

This example shows the output returned by neptune.read using the following query:

aws neptune-graph execute-query \ 
--graph-identifier ${graphIdentifier} \ 
--query-string "CALL neptune.read({source: '<s3 path>', format: 'csv'}) YIELD row RETURN row" \ 
--language open_cypher \
 /tmp/out.txt 
 
 
cat /tmp/out.txt

Currently, there is no way to set a node or edge label to a data field coming from a csv file. It is recommended that you partition the queries into multiple queries, one for each label/type.

CALL neptune.read({source: '<s3 path>', format: 'csv'})
 YIELD row 
WHERE row.`~label` = 'airport'
CREATE (n:airport)

CALL neptune.read({source: '<s3 path>', format: 'csv'})
YIELD row 
WHERE row.`~label` = 'country'
CREATE (n:country)
