Xiangrui Meng created SPARK-8345: ------------------------------------ Summary: Add an SQL node as a feature tranformer Key: SPARK-8345 URL: https://issues.apache.org/jira/browse/SPARK-8345 Project: Spark Issue Type: New Feature Components: ML Reporter: Xiangrui Meng
Some simple feature transformations can take leverage on SQL operators. Users do not need to create an ML transformer for each of them. We can have an SQL transformer that executes an SQL command which operates on the input dataframe. {code} val sql = new SQL() .setStatement("SELECT *, length(text) AS text_length FROM __THIS__") {code} where "__THIS__" will be replaced by a temp table that represents the DataFrame. -- 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
