> LazySimple Timestamp and Date serialization is very expensive

> Key: HIVE-17417
> URL: https://issues.apache.org/jira/browse/HIVE-17417
> Project: Hive
> Issue Type: Bug
> Components: Serializers/Deserializers
> Affects Versions: 3.0.0, 2.4.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Critical
> Attachments: date-serialize.png, HIVE-17417.1.patch,

>
>
> In a specific case where a schema contains array<struct> with timestamp and
> date fields (array size >10000). Any access to this column very very
> expensive in terms of CPU as most of the time is serialization of timestamp
> and date. Refer attached profiles. >70% time spent in serialization +
> tostring conversions.
