Apache Ignite Spring Module
---------------------------
Apache Ignite Spring Data 2.2 extension provides an integration with Spring Data 2.2 framework.
Main features:
- 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).
