holdenk commented on SPARK-15369: --------------------------------- I can understand the hesitancy to adopt this long term - I wish we could explore exposing this as a developer API instead but if that isn't something of interest I'll take a look at adding this as a spark package (or adding to one of the meta-spark packages like Bahir). In the meantime I'll do some more poking with Arrow and see if its getting to a point where we could selectively start using it in PySpark. > Investigate selectively using Jython for parts of PySpark > --------------------------------------------------------- > > Key: SPARK-15369 > URL: https://issues.apache.org/jira/browse/SPARK-15369 > Project: Spark > Issue Type: Improvement > Components: PySpark > Reporter: holdenk > Priority: Minor > > Transferring data from the JVM to the Python executor can be a substantial > bottleneck. While Jython is not suitable for all UDFs or map functions, it > may be suitable for some simple ones. We should investigate the option of > using Jython to accelerate these small functions. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
