>          Issue Type: Improvement
>          Components: spring

> I have it working for Spring Data 2 (2.7.6) module with some interesting improvements, but by now I don't have enough time to give it the attention it requires, full unit/integration tests..., sorry a lot. ¿maybe any of you have the time?. Thanks community!!
> Code is 100% compatible with previous versions. [https://github.com/hawkore/ignite-hk/tree/master/modules/spring-data-2.0]
>  * Supports multiple ignite instances on same JVM (@RepositoryConfig).
>  * Supports query tuning parameters in {{@Query}} annotation
>  * Supports projections
>  * Supports {{Page}} and {{Stream}} responses
>  * Supports Sql Fields Query resultset transformation into the domain entity
>  * Supports named parameters ({{:myParam}}) into SQL queries, declared using {{@Param("myParam")}}
>  * Supports advanced parameter binding and SpEL expressions into SQL queries:
>  ** *Template variables*:
>  *** {{#entityName}} - the simple class name of the domain entity
>  ** *Method parameter expressions*: Parameters are exposed for indexed access ({{[0]}} is the first query method's param) or via the name declared using {{@Param}}. The actual SpEL expression binding is triggered by {{?#}}. Example: {{?#\{[0]\}} or {{?#\{#myParamName\}}}
>  ** *Advanced SpEL expressions*: While advanced parameter binding is a very useful feature, the real power of SpEL stems from the fact, that the expressions can refer to framework abstractions or other application components through SpEL EvaluationContext extension model.
>  * Supports SpEL expressions into Text queries ({{TextQuery}}). 
> Some examples:
> {code:java}
> // Spring Data Repositories using different ignite instances on same JVM
> @RepositoryConfig(igniteInstance = "FLIGHTS_BBDD", cacheName = "ROUTES")
> public interface FlightRouteRepository extends IgniteRepository<Route, String> {
> ...
> }
> @RepositoryConfig(igniteInstance = "GEO_BBDD", cacheName = "POIS")
> public interface PoiRepository extends IgniteRepository<Poi, String> {
> ...
> }
> {code}
> {code:java}
> // named parameter
> @Query(value = "SELECT * from #{#entityName} where email = :email")
> User searchUserByEmail(@Param("email") String email);
> {code}
> {code:java}
> // indexed parameters
> @Query(value = "SELECT * from #{#entityName} where country = ?#{[0] and city = ?#{[1]}")
> List<User> searchUsersByCity(@Param("country") String country, @Param("city") String city, Pageable pageable);
> {code}
> {code:java}
> // ordered method parameters
> @Query(value = "SELECT * from #{#entityName} where email = ?")
> User searchUserByEmail(String email);
> {code}
> {code:java}
> // Advanced SpEL expressions
> @Query(value = "SELECT * from #{#entityName} where uuidCity = ?#{mySpELFunctionsBean.cityNameToUUID(#city)}")
> List<User> searchUsersByCity(@Param("city") String city, Pageable pageable);
> {code}
> {code:java}
> // textQuery - evaluated SpEL named parameter
> @Query(textQuery = true, value = "email: #{#email}")
> User searchUserByEmail(@Param("email") String email);
> {code}
> {code:java}
> // textQuery - evaluated SpEL named parameter
> @Query(textQuery = true, value = "#{#textToSearch}")
> List<User> searchUsersByText(@Param("textToSearch") String text, Pageable pageable);

> // Projection
> @Query(value =
>                "SELECT DISTINCT m.id, m.name, m.logos FROM #{#entityName} e USE INDEX (ORIGIN_IDX) INNER JOIN \"flightMerchants\".Merchant m ON m"
>                    + "._key=e"
>                    + ".merchant WHERE e.origin = :origin and e.disabled = :disabled GROUP BY m.id, m.name, m.logos ORDER BY m.name")
> <P> List<P> searchMerchantsByOrigin(Class<P> projection, @Param("origin") String origin, @Param("disabled") boolean disabled);
