Summary: Iterators in columnSimilarities to allow flatMap spill
Key: SPARK-6713
URL: https://issues.apache.org/jira/browse/SPARK-6713
Project: Spark
Issue Type: Improvement
Components: MLlib
Reporter: Reza Zadeh
We should use Iterators in columnSimilarities to allow flatMap to spill to
disk. This could happen in a dense and large column - this way Spark can spill
the pairs onto disk instead of building all the pairs before handing them to
Spark.
