Kartik Somani commented on IGNITE-12702:
----------------------------------------
When should the warning be triggered? build time, cache creation
(getOrCreateCache) or at the time of calling put for the cache? (thats when the
annotation is actually used in case of key) ?
> Print warning when a cache value contains @AffinityKeyMapped annotation

> Key: IGNITE-12702
> URL: https://issues.apache.org/jira/browse/IGNITE-12702
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Reporter: Denis Mekhanikov
> Assignee: Kartik Somani
> Priority: Major
> Labels: newbie
>
> Consider the following code snippet:
> {code:java}
> public class WrongAffinityExample {
> public static void main(String[] args) {
> Ignite ignite = Ignition.start("config/ignite.xml");
> IgniteCache<EmployeeKey, EmployeeValue> cache =
> ignite.getOrCreateCache("employees");
> EmployeeKey key = new EmployeeKey(1);
> EmployeeValue value = new EmployeeValue(1, "Denis");
> cache.put(key, value);
> }
> public static class EmployeeKey {
> private int id;
> public EmployeeKey(int id) {
> this.id = id;
> }
> }
> public static class EmployeeValue {
> @AffinityKeyMapped
> int departmentId;
> String name;
> public EmployeeValue(int departmentId, String name) {
> this.departmentId = departmentId;
> this.name = name;
> }
> }
> }
> {code}
> Note, that {{EmployeeValue}} contains an {{@AffinityKeyMapped}} annotation,
> which doesn't have any effect, since it's specified in a value, and not in a
> key.
> Such mistake is simple to make and pretty hard to track down.
> This configuration should trigger a warning message printed in log to let
> the user know that this affinity key configuration is not applied.
