-Changelog is a feature that aims to decrease checkpointing time and, therefore, end-to-end latency in exactly-once mode.
+<a name="introduction"></a>
 
-Most commonly, checkpoint duration is affected by:
+### 介绍
 
-1. Barrier travel time and alignment, addressed by
-   [Unaligned checkpoints]({{< ref "docs/ops/state/checkpointing_under_backpressure#unaligned-checkpoints" >}})
-   and [Buffer debloating]({{< ref "docs/ops/state/checkpointing_under_backpressure#buffer-debloating" >}})
-2. Snapshot creation time (so-called synchronous phase), addressed by asynchronous snapshots (mentioned [above]({{<
-   ref "#the-embeddedrocksdbstatebackend">}}))
-4. Snapshot upload time (asynchronous phase)
+Changelog 是一项旨在减少 checkpointing 时间的功能，因此也可以减少 exactly-once 模式下的端到端延迟。
 
-Upload time can be decreased by [incremental checkpoints]({{< ref "#incremental-checkpoints" >}}).
-However, most incremental state backends perform some form of compaction periodically, which results in re-uploading the
-old state in addition to the new changes. In large deployments, the probability of at least one task uploading lots of
-data tends to be very high in every checkpoint.
+一般情况下 checkpoint 持续时间受如下因素影响：
 
-With Changelog enabled, Flink uploads state changes continuously and forms a changelog. On checkpoint, only the relevant
-part of this changelog needs to be uploaded. The configured state backend is snapshotted in the
-background periodically. Upon successful upload, the changelog is truncated.
+1. Barrier 到达和对齐时间，可以通过 [Unaligned checkpoints]({{< ref "docs/ops/state/checkpointing_under_backpressure#unaligned-checkpoints" >}}) and [Buffer debloating]({{< ref "docs/ops/state/checkpointing_under_backpressure#buffer-debloating" >}}) 解决。

   Sorry , it's my oversight, I will fix it.
