Krishna Kumar updated HIVE-956: ------------------------------- Attachment: HIVE.956.patch.1 Patch with a change on how null vs empty strings are handled. This patch uses a special single-byte marker (which is not a valid utf-8 byte sequence) to mark empty strings. With this patch, this serde is better than the default serde - for all primitive types - also when null values preponderate while performing about the same for complex structures such as list of structs et al. Please review. > Add support of columnar binary serde > ------------------------------------ > > Key: HIVE-956 > URL: https://issues.apache.org/jira/browse/HIVE-956 > Project: Hive > Issue Type: New Feature > Reporter: He Yongqiang > Assignee: Krishna Kumar > Attachments: HIVE.956.patch.0, HIVE.956.patch.1 > > -- This message is automatically generated by JIRA.
