> We have a pretty ignite-spring-data integration but we don't have a
> support of `QuerydslPredicateExecutor` which provide ability to filter
> cache entities by dynamic criterias.
>
> Example of usage:
>
> {code:java}
> /**
> * Simple entity.
> */
> @QueryEntity
> public class Person {
>     /** First name. */
>     @QuerySqlField(index = true)
>     private String firstName;
>
>     /** Second name. */
>     @QuerySqlField(index = true)
>     private String secondName;
>
>     /** Age. **/
>     @QuerySqlField(index = true)
>     private int age;
> }
>
> /**
> * Implement QuerydslPredicateExecutor interface.
> */
> public interface PersonRepository extends IgniteRepository<Person,
> Integer>, QuerydslPredicateExecutor<Person> {
>
> }
>
> /**
> * Now we can filter our entites by firstName prdicate.
> */
> List<Person> persons = (List<Person>) repo.findAll(
>         QPerson.person.firstName.eq(firstName_1)
>             .or(QPerson.person.firstName.eq(firstName_2))
> );
> {code}
