             Summary: Column's type mismatch during marshalling of pojo
                 Key: IGNITE-21797
                 URL: https://issues.apache.org/jira/browse/IGNITE-21797
             Project: Ignite
          Issue Type: Bug
            Reporter: Konstantin Orlov


Take a look at the scenario below:

{code:java}
    static class Key {
        int int_col;
        String str_col;
    }

    static class Val {
        boolean bool_col;
        LocalDate date_col;
    }

    sql("CREATE TABLE test (int_col INT, bool_col BOOLEAN, date_col DATE, str_col VARCHAR, PRIMARY KEY (int_col, str_col))");

    KeyValueView<Key, Val> kvView = CLUSTER.aliveNode().tables()
            .table("test")
            .keyValueView(Key.class, Val.class);

    var key = new Key();
    key.int_col = 1;
    key.str_col = "1";

    var val = new Val();
    val.bool_col = true;
    val.date_col = LocalDate.now();

    kvView.put(null, key, val);
{code}
Mind the order of primary key fields: the first and the last columns in table declaration. In that case, {{InvalidTypeException}} is thrown, because after IGNITE-19744 key columns are not grouped in the very beginning of the row anymore, but marshaller of embedded client still appends key columns first (see {{org.apache.ignite.internal.schema.marshaller.reflection.KvMarshallerImpl#marshal(K, V)}}).
