[csv-to-neptune-bulk-format] : upsert

[chetanpatilofficial]

I have a scenario where I want to upsert the node properties whenever we have multiple record with same key but change in property values. I tried to test this scenario by modifying the Spotify dataset(modified track_popularity) like below for Track Node:

But as this is a duplicate record as per the uniqueKey, final Track.csv is not generating both the record.

Is there anyway using csv-to-neptune-bulk-format utility i can upsert if same uniqueKey record present in incoming data csv ?

You can use the bulk loader for upserts under two conditions:

• The value for a given property is of single cardinality [1]
• The bulk load request is submitted with the updateSingleCardinalityProperties parameter set to TRUE [2]

You would also need to change the csv-to-neptune config file so that the properties that you want to update are single cardinality (or, isMultiValue = false).
