Please show your producer's code.
The following is an example, please refer to
```
@Builder
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Foo3 {
public String field1;
public String field2;
public int field3;
}
PulsarClient client = PulsarClient.builder()
.serviceUrl("pulsar://localhost:6650")
.build();
AvroSchema schema =
AvroSchema.of(SchemaDefinition.builder().withPojo(Foo3.class).withAlwaysAllowNull(false).build());
Producer producer = client.newProducer(schema)
.topic("test-jdbc")
.create();
for (int i = 0; i < 20; i++) {
String key = "key-" + i;
Foo3 obj = new Foo3();
obj.setField1("field1_insert_" + i);
obj.setField2("field2_insert_" + i);
obj.setField3(i);
Map properties = Maps.newHashMap();
properties.put("EVENT", "INSERT");
producer.newMessage()
.properties(properties)
.key(key)
.value(obj)
.send();
}
for (int i = 0; i < 20; i++) {
String key = "key-" + i;
Foo3 obj = new Foo3();
obj.setField1("field1_insert_" + i);
obj.setField2("field2_update_" + i);
obj.setField3(i);
Map properties = Maps.newHashMap();
properties.put("EVENT", "UPDATE");
producer.newMessage()
.properties(properties)
.key(key)
.value(obj)
.send();
}
for (int i = 0; i < 20; i++) {
String key = "key-" + i;
Foo3 obj = new Foo3();
obj.setField1("field1_insert_" + i);
obj.setField2("field2_delete_" + i);
obj.setField3(i);
Map properties = Maps.newHashMap();
properties.put("EVENT", "DELETE");
producer.newMessage()
.properties(properties)
.key(key)
.value(obj)
.send();
}
producer.close();
client.close();
