Example 11 with SchemaAndValue

use of org.apache.kafka.connect.data.SchemaAndValue in project kafka by apache.

the class JsonConverterTest method decimalToConnect.

@Test
public void decimalToConnect() {
    Schema schema = Decimal.schema(2);
    BigDecimal reference = new BigDecimal(new BigInteger("156"), 2);
    // Payload is base64 encoded byte[]{0, -100}, which is the two's complement encoding of 156.
    String msg = "{ \"schema\": { \"type\": \"bytes\", \"name\": \"org.apache.kafka.connect.data.Decimal\", \"version\": 1, \"parameters\": { \"scale\": \"2\" } }, \"payload\": \"AJw=\" }";
    SchemaAndValue schemaAndValue = converter.toConnectData(TOPIC, msg.getBytes());
    BigDecimal converted = (BigDecimal) schemaAndValue.value();
    assertEquals(schema, schemaAndValue.schema());
    assertEquals(reference, converted);
}

Example 12 with SchemaAndValue

use of org.apache.kafka.connect.data.SchemaAndValue in project kafka by apache.

the class JsonConverterTest method decimalToConnectWithDefaultValue.

@Test
public void decimalToConnectWithDefaultValue() {
    BigDecimal reference = new BigDecimal(new BigInteger("156"), 2);
    Schema schema = Decimal.builder(2).defaultValue(reference).build();
    String msg = "{ \"schema\": { \"type\": \"bytes\", \"name\": \"org.apache.kafka.connect.data.Decimal\", \"version\": 1, \"default\": \"AJw=\", \"parameters\": { \"scale\": \"2\" } }, \"payload\": null }";
    SchemaAndValue schemaAndValue = converter.toConnectData(TOPIC, msg.getBytes());

    assertEquals(reference, schemaAndValue.value());
}

Example 13 with SchemaAndValue

use of org.apache.kafka.connect.data.SchemaAndValue in project kafka by apache.

the class JsonConverterTest method nullSchemaPrimitiveToConnect.

@Test
public void nullSchemaPrimitiveToConnect() {
    SchemaAndValue converted = converter.toConnectData(TOPIC, "{ \"schema\": null, \"payload\": null }".getBytes());
    assertEquals(SchemaAndValue.NULL, converted);
    converted = converter.toConnectData(TOPIC, "{ \"schema\": null, \"payload\": true }".getBytes());
    assertEquals(new SchemaAndValue(null, true), converted);
    // Integers: Connect has more data types, and JSON unfortunately mixes all number types. We try to preserve
    // info as best we can, so we always use the largest integer and floating point numbers we can and have Jackson
    // determine if it's an integer or not
    converted = converter.toConnectData(TOPIC, "{ \"schema\": null, \"payload\": 12 }".getBytes());
    assertEquals(new SchemaAndValue(null, 12L), converted);
    converted = converter.toConnectData(TOPIC, "{ \"schema\": null, \"payload\": 12.24 }".getBytes());
    assertEquals(new SchemaAndValue(null, 12.24), converted);
    converted = converter.toConnectData(TOPIC, "{ \"schema\": null, \"payload\": \"a string\" }".getBytes());
    assertEquals(new SchemaAndValue(null, "a string"), converted);
    converted = converter.toConnectData(TOPIC, "{ \"schema\": null, \"payload\": [1, \"2\", 3] }".getBytes());
    assertEquals(new SchemaAndValue(null, Arrays.asList(1L, "2", 3L)), converted);
    converted = converter.toConnectData(TOPIC, "{ \"schema\": null, \"payload\": { \"field1\": 1, \"field2\": 2} }".getBytes());
    Map<String, Long> obj = new HashMap<>();
    obj.put("field1", 1L);
    obj.put("field2", 2L);
    assertEquals(new SchemaAndValue(null, obj), converted);
}

Example 14 with SchemaAndValue

use of org.apache.kafka.connect.data.SchemaAndValue in project kafka by apache.

    SchemaAndValue schemaAndValue = converter.toConnectData(TOPIC, msg.getBytes());
    assertEquals(schema, schemaAndValue.schema());
    assertNull(schemaAndValue.value());
}
