Yury Gerzhedovich updated IGNITE-15787:
---------------------------------------
Parent: (was: IGNITE-15782)
Issue Type: Improvement (was: Sub-task)
> Add annotation support to POJO Mappers.
> ---------------------------------------
>
> Key: IGNITE-15787
> URL: https://issues.apache.org/jira/browse/IGNITE-15787
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Andrey Mashenkov
> Priority: Major
> Labels: ignite-3
>
> Let's introduce annotations for mapper builder.
> Suggested annotations:
> * Transient - that makes mapper ignore the marked field. Field data will not
> be saved into a table.
> * Column(String) - maps field to a field of the given name.
> * Column(Class) - maps field to a field of given name using converter class.
> This will allow users to create mapper like this
> {code:java}
> class Record {
> @Transient
> transient Object cachedData;
> @Column(UserMarshaller.class)
> UseObject value;
> @Column("key")
> UUID id;
> }
> Mappers.forClass(Record.class)
> {code}
> instead of like this
> {code:java}
> Mappers.of(Record.class)
> .map("id", "key")
> .map("value",
> (obj) -> Marshaller.marshal(obj),
> (row) -> Marshaller.unmarshal(row)
> );
> {code}
