Sink function 会把准备发到 PubSub 的信息短暂地缓存以提高性能。每次 checkpoint
前，它会刷新缓冲区，并且只有当所有信息成功发送到 PubSub 之后，checkpoint 才会成功完成。
-## 常见问题
-
-由于Pulsar Connector大量依赖
-[PulsarClient](https://pulsar.apache.org/docs/en/client-libraries-java/) 和
-[PulsarAdmin](https://pulsar.apache.org/docs/en/admin-api-overview/)
来实现相关功能，有时Flink Job出现
-可能是由于Pulsar broker版本过低或者配置不合适导致的。调试配置或升级pulsar可能会解决部分问题。
-
-
-### 当数据量很小时，source读数据出现大约10s延迟
-
-当Pulsar Source从一个数据量很小的topic读取数据时，用户可能会观测到消息间出现10秒钟的间隔。这是由于Pulsar Source
-会将从broker读到的消息暂存至等待队列中，只有当队列中消息数量达到了
`PulsarSourceOptions.PULSAR_MAX_FETCH_RECORDS`
-才会向下游算子发送数据。如果数据量一直很小，那么就会在等待直到等待时长超过`PULSAR_MAX_FETCH_TIME`规定的值 (默认10秒钟)时
-也向下游算子发送数据。
-
-为了避免这种情况，用户需要改变两个配置项的值。
