Michael Armbrust resolved SPARK-6674. ------------------------------------- Resolution: Duplicate > Use different types to represent rows used inside and outside Catalyst > ---------------------------------------------------------------------- > > Key: SPARK-6674 > URL: https://issues.apache.org/jira/browse/SPARK-6674 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 1.1.1, 1.2.1, 1.3.0 > Reporter: Cheng Lian > > Within Catalyst, we use more efficient classes to represent objects in rows. > For example, we use {{o.a.s.sql.types.Decimal}} instead of Java > {{BigDecimal}}. When row objects are passed to / from user space, these > object get converted by {{ScalaReflection.convertToScala}} / > {{ScalaReflection.converToCatalyst}}. > This approach is error prone because we may occasionally forget to add > necessary conversions. It would be better to have a dedicated row type to > represent row objects used within Catalyst, thus enforce this convention via > type system. -- 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
