> Cannot create caches with different names but with same indexed types and
> schema name. In this case "javax.cache.CacheException: Index already exists:
> PERSON_ORGID_IDX" wil be thrown (Value has field with "origId" and annotation
> @QuerySqlField(index = true)).
>
> {code:java}
> node.createCache(new CacheConfiguration<PersonKey, Person>()
> .setName("PERSON_1")
> .setQueryEntities(Arrays.asList(new QueryEntity(PersonKey.class,
> Person.class).setTableName("PERSON_1")))
> .setSqlSchema(QueryUtils.DFLT_SCHEMA));
> node.createCache(new CacheConfiguration<PersonKey, Person>()
> .setName("PERSON_2")
> .setQueryEntities(Arrays.asList(new QueryEntity(PersonKey.class,
> Person.class).setTableName("PERSON_2")))
> .setSqlSchema(QueryUtils.DFLT_SCHEMA));
> {code}
>
> Here is definition of Person class:
>
> {code:java}
> public static class PersonKey {
> @QuerySqlField
> public long id;
> /**
> * Constructor.
> *
> * @param id ID.
> */
> PersonKey(long id) {
> this.id = id;
> }
> /** {@inheritDoc} */
> Override public int hashCode() {
> return (int)id;
> }
> /** {@inheritDoc} */
> @Override public boolean equals(Object obj) {
> return obj != null && obj instanceof PersonKey && (F.eq(id,
> ((PersonKey)obj).id));
> }
> }{code}
> Such behavior seems to be usability bug. Why I cannot create two caches with
> different names but with same indexed values?
