Example 1 with PersistenceSchema

use of io.confluent.ksql.schema.ksql.PersistenceSchema in project ksql by confluentinc.

the class KsqlDelimitedDeserializerTest method shouldThrowOnStructTypes.

@Test
public void shouldThrowOnStructTypes() {
    // Given:
    final PersistenceSchema schema = persistenceSchema(column("ids", SqlTypes.struct().field("f0", SqlTypes.INTEGER).build()));
    // When:
    final Exception e = assertThrows(KsqlException.class, () -> createDeserializer(schema));
    // Then:
    assertThat(e.getMessage(), containsString("The 'DELIMITED' format does not support type 'STRUCT', column: `ids`"));
}

    final KsqlDelimitedDeserializer deserializer = createDeserializer(schema);
    final byte[] bytes = "\"-01.12\"".getBytes(StandardCharsets.UTF_8);
    // When:
    final List<?> result = deserializer.deserialize("", bytes);
    // Then:
