It can be easily reproduced by following.
```
func TestSchemaStuck(t *testing.T) {
client, err := NewClient(ClientOptions{
URL: lookupURL,
})
assert.NoError(t, err)
defer client.Close()
schema1 := NewAvroSchema(`{"fields":
[
{"name":"id","type":"int"},{"default":null,"name":"name","type":["null","string"]}
],
"name":"MyAvro3","namespace":"PulsarTestCase","type":"record"}`, nil)
schema2 := NewAvroSchema(`{"fields":
[
{"name":"id","type":"int"},{"default":null,"name":"name","type":["null","string"]},
{"default":null,"name":"age","type":["null","int"]}
],"name":"MyAvro3","namespace":"PulsarTestCase","type":"record"}`, nil)
v1 := map[string]interface{}{
"id": 1,
"name": map[string]interface{}{
"string": "aac",
},
}
v2 := map[string]interface{}{
"id": 1,
"name": map[string]interface{}{
"string": "test",
},
"age": map[string]interface{}{
"int": 10,
},
}
topic := newTopicName()
producer, err := client.CreateProducer(ProducerOptions{
Topic: topic,
Schema: schema1,
DisableMultiSchema: true,
})
assert.NoError(t, err)
assert.NotNil(t, producer)
defer producer.Close()
for i := 0; i < 10; i++ {
var messageContent []byte
var key string
var schema Schema
if i%2 == 0 {
messageContent, err = schema1.Encode(v1)
key = "v1"
schema = schema1
assert.NoError(t, err)
} else {
messageContent, err = schema2.Encode(v2)
key = "v2"
schema = schema2
assert.NoError(t, err)
}
_, err = producer.Send(context.Background(), &ProducerMessage{
Payload: messageContent,
Key: key,
Schema: schema,
})
}
producer.Flush()
}
```
