Hello Raj, Thank you so much for explanation regarding this question.
I have another question for you: Does apache ignite 3.0.0 have full spring support or will it have in the future? Because ignite-spring only goes up to 2.17.

This significant change affects how you define queryable fields in your domain models. For Ignite 3.0.0, the recommended approach is to use the new Table API instead of annotations. In this new model, you define tables programmatically rather than using annotations on your Java classes. Here's how you can transition from the annotation-based approach to the new Table API: 1. Instead of annotating fields with `@QuerySqlField`, you'll now create table definitions using `TableDescriptor` and the fluent API. 2. Basic example of creating a table in Ignite 3.0.0: ```java TableDescriptor table = TableDescriptor.builder() .name("MyTable") .addColumn("id", ColumnType.INT32, true) // primary key .addColumn("name", ColumnType.STRING) .addColumn("age", ColumnType.INT32) .build(); tables.createTable(table).get(); ``` 3. For working with the data, you'll use the Table API methods for CRUD operations rather than putting/getting annotated objects. The shift from 2.x to 3.0.0 is substantial and requires rethinking your data model approach. The new version moves away from the "object in the cache" model toward a more traditional table-based database approach. If you have a significant investment in the annotation-based approach and need to maintain compatibility, you might consider: 1. Staying on Ignite 2.x for the time being 2. Creating an abstraction layer in your code to isolate the Ignite-specific parts, making future migration easier 3. Gradually migrating components to use the new Table API while maintaining the old components on 2.x The Ignite 3.0 documentation provides comprehensive guidance on the new Table API and migration strategies from 2.x.
