Partial Updates on index using Spark Streaming

(Darshan Shah) #1

down vote
I am using following command to persist data in elastic search using spark streaming.

EsSparkSQL.saveToEs(DataFrame, indexname, ES_CONFIG)
With this, I am overwriting entire document, which I don't want.

I want to update only the fields for which data exists in this dataframe.

Please suggest, How to achieve this...
