> Key: IGNITE-9819
> URL: https://issues.apache.org/jira/browse/IGNITE-9819
> Project: Ignite
> Issue Type: Task
> Components: documentation
> Reporter: Vladimir Ozerov
> Assignee: Artem Budnikov
> Priority: Major
> Fix For: 2.7
>
>
> We support both DATE (date only) and TIMESTAMP (date + time) data types.
> Unfortunately, DATE data type is serialized/deserialized very inefficiently,
> what leads to performance degradation.
> We need to warn users in documentation, that it is better to use TIMESTAMP
> than DATE.
