Hi all, I wondered the cast cost from Spark Vectors to Breeze vector is high or low. So I benchmarked the simple operation about addition, multiplication and division of RDD[Vector] or RDD[BV[Double]]. I share the simple benchmark result with you.
In conclusion, the cast cost was lower than I had expected.
