Change subject: IMPALA-5572: Timestamp codegen for text scanner ...................................................................... IMPALA-5572: Timestamp codegen for text scanner Currently codegen is disabled when scanning text tables with timestamp columns. The message is "Timestamp not yet supported for codegen." This patch adds support for timestamp codegen. A simple query in the comment section of this issue performs a little better (4%) than interpreted version.
