> ### Motivation

> About pattern subscribes of consumers, the `topicsPattern` and
> `subscribeTopicMode` configurations are contradictory.
>
> For example, the `topicsPattern` represents only subscription to
> `persistent topic`, but the `subscriptionTopicsMode` represents
> subscription to `all topic`.
>
> ``` java
> Pattern pattern =
> Pattern.compile("persistent://my-property/my-ns/pattern-topic.*");
> Consumer<byte[]> consumer = pulsarClient.newConsumer()
> .topicsPattern(pattern)
> .subscriptionTopicsMode(RegexSubscriptionMode.AllTopics)
> .build();
> ```
>
> Finally, `all topics` are subscribed. It's very confusing.
