Xiao Li created SPARK-16157: ------------------------------- Summary: Add New Methods for Comments in StructField and StructType Key: SPARK-16157 URL: https://issues.apache.org/jira/browse/SPARK-16157 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 2.0.0 Reporter: Xiao Li
Currently, the column-related comment attribute is stored in {{Metadata}}. For example, {{noformat}} StructType( StructField("cl1", IntegerType, nullable = false, new MetadataBuilder().putString("comment", "test").build()) :: Nil) {{noformat}} Compared with the existing SQL interface, it is not user friendly to add such a comment attribute when defining a {{StructField}}. -- 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
