[jira] [Resolved] (IGNITE-1039) Need to inspect nested objects for indexing automatically

["Vladimir Ozerov (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-1039?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vladimir Ozerov resolved IGNITE-1039.
-------------------------------------
    Resolution: Won't Fix

This doesn't work in general case. E.g. {{Organization}} may be a root of object hierarchy, and some other {{FinancialOrganization extends Organization}} may have other SQL fields which we will miss. 

Another problem is that user will not be able to have nested class with query fields which he do not want to add to the table (the opposite situation).

For this reason it is better to keep things simple and do not rely on reflection which is out of our control.

>             Project: Ignite
>          Issue Type: Bug
>          Components: cache, sql
>    Affects Versions: sprint-4

>            Priority: Major
>              Labels: Usability, sql

> Imagine we have this data model with {{Organization}} object nested into {{Person}}:
> {code}
> Person {
>     @QuerySqlField
>     String name;
>     Organization org;
> }
> Organization {
>     @QuerySqlField
>     String name;
> }
> {code}
> This currently doesn't work because {{Organization}} is not inspected until we put {{@QuerySqlField}} annotation on {{Person.org}} field.
> Such design is not good because it is:
> * Counterintuitive
> * Adds {{org}} field to tables which is not needed.
> We should inspect nested objects automatically.
