level and cannot be matched to the partition level. Because the partition is
invisible to the user.

2019-06-14 11:37:50 UTC - Bharadwaj R Embar: @xiaolong.ran I’ll make this
simpler. I have one topic which is non-partitioned. I’m trying to use the same
regex based subscription.
```
Producer Side:
Topic:
my-topic
```
```
Consumer Side:
consumerOpts := pulsar.ConsumerOptions{
TopicsPattern: "my-topic*",
SubscriptionName: "my-sub",
Type: pulsar.Exclusive,
MessageChannel: msgChannel,
SubscriptionInitPos: pulsar.Earliest,
}
```
Consume logic:
```
for cm := range msgChannel {
msg := cm.Message
fmt.Println("Message ID: %s", msg.ID())
fmt.Println("Got Message value: %s from : %s",
string(msg.Payload()), msg.Topic())
consumer.Ack(msg)
}
```
Still does not consume, instead it just hangs after saying connected to broker

2019-06-14 11:43:02 UTC - xiaolong.ran: Look at the log information, it feels
like the pattern does not match the appropriate topic
----
2019-06-14 11:44:56 UTC - xiaolong.ran: Or, can you give me a simple test code?
It’s best to reproduce the problem you’re experiencing.

2019-06-14 12:08:42 UTC - Bharadwaj R Embar: Big ups to @xiaolong.ran for
quickly resolving the issue. I only gave the topic regex and not the fqdn of
the topic , ie, `topic*` and not `<persistent://public/default/topic*>`. We
need to specify the fqdn of the topics we wish to subscribe. Thanks again
