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
