If they get an array, an map, or an struct from a {{Unsafe}} related > data structure, it is inefficient. > This JIRA prepares a new implementation {{OnHeapUnsafeColumnarVector}} that > is optimized for reading data from a {{Unsafe}} related data structure. -- 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
