Ksenia Rybakova updated IGNITE-4456:
------------------------------------
Description:
Example:
{code}
CacheConfiguration<AffinityKey<Long>, Person> personCacheCfg = new
CacheConfiguration<>("Persons");
personCacheCfg.setCacheMode(CacheMode.PARTITIONED);
...
public AffinityKey<Long> key() {
if (key == null)
key = new AffinityKey<>(id, orgId);
return key;
}
{code}
Currently it's not obvious that in such a case we should:
1) Use QueryEntity to specify {{key}} and {{affKey}} as key fields as it's
described in https://apacheignite.readme.io/docs/dml#section-custom-keys
2) Use {{key}} and {{affKey}} in statements directly instead of {{_key}}:
{code}
"INSERT INTO Person(key, affKey, firstName, lastName, resume, salary, orgId)
VALUES (42, 2, 'Ivan', 'Ivanov', 'Ivan Ivanov has no
degree', CAST(300 AS DOUBLE), 2)"
{code}
