-# Unaligned checkpoints
+# Checkpointing under backpressure
+
+Normally aligned checkpointing time is dominated by the synchronous and asynchronous parts of the
+checkpointing process. However, when Flink job is running under a heavy backpressure, the dominant
+factor in the end to end time of a checkpoint can be the time to propagate checkpoint barriers to
+all operators/subtasks (why this is the case is explained in the overview of the
+[checkpointing process]({{< ref "docs/concepts/stateful-stream-processing" >}}#checkpointing)).
+This can be observed by high
+[alignment time and start delay metrics]({{< ref "docs/ops/monitoring/checkpoint_monitoring" >}}#history-tab).
+When this happens and becomes an issue there are basically three ways to address this problem:
+1. Remove the source of the backpressure, by either optimising the Flink job, adjusting Flink or JVM configuration or simply by scaling up.
+2. Reduce an amount of the buffered in-flight data in the Flink job.
+3. Enable unaligned checkpoints.
+
+Note that those options are not mutually exclusive, and you can combine them together. This document
+focuses on the latter two options.
+
+## Buffer debloating
+
+Flink 1.14 introduced a new tool to automatically control an amount of the buffered in-flight data
+between Flink operators/subtasks. The buffer debloating mechanism can be enabled by setting the property
+`taskmanager.network.memory.buffer-debloat.enabled` to `true`. How does it work and how to configure
+it is described in more details in the [network memory tuning guide]({{< ref "docs/deployment/memory/network_mem_tuning" >}}#the-buffer-debloating-mechanism).
+
+This feature works both with aligned and unaligned checkpoints and can improve checkpointing times
+in both cases, but the effect of the debloating is most easily visible with aligned checkpoints.
+When using buffer debloating with unaligned checkpoints, the added benefit will be smaller checkpoints
+size and quicker recovery times (there will be less in-flight data to persist and recover).
+
+Keep in mind that you can also manually reduce the amount of the buffered in-flight data. How to do
+just that is also described in the aforementioned
+[network memory tuning guide]({{< ref "docs/deployment/memory/network_mem_tuning" >}}).

- *externalized checkpoints*: You can configure periodic checkpoints to be persisted externally. Externalized checkpoints write their meta data out to persistent storage and are *not* automatically cleaned up when the job fails. This way, you will have a checkpoint around to resume from if your job fails. There are more details in the [deployment notes on externalized checkpoints]({{< ref "docs/ops/state/checkpoints" >}}#externalized-checkpoints).
- - *unaligned checkpoints*: You can enable [unaligned checkpoints]({{< ref "docs/ops/state/unaligned_checkpoints" >}}) to greatly reduce checkpointing times under backpressure. This only works for exactly-once checkpoints and with number of concurrent checkpoints of 1.

-# Unaligned checkpoints
+# Checkpointing under backpressure
+
+Normally aligned checkpointing time is dominated by the synchronous and asynchronous parts of the
+checkpointing process. However, when Flink job is running under a heavy backpressure, the dominant
+factor in the end to end time of a checkpoint can be the time to propagate checkpoint barriers to
+all operators/subtasks (why this is the case is explained in the overview of the
+[checkpointing process]({{< ref "docs/concepts/stateful-stream-processing" >}}#checkpointing)).
+This can be observed by high
+[alignment time and start delay metrics]({{< ref "docs/ops/monitoring/checkpoint_monitoring" >}}#history-tab).
+When this happens and becomes an issue there are basically three ways to address this problem:
+1. Remove the source of the backpressure, by either optimising the Flink job, adjusting Flink or JVM configuration or simply by scaling up.
+2. Reduce an amount of the buffered in-flight data in the Flink job.
+3. Enable unaligned checkpoints.
+
+Note that those options are not mutually exclusive, and you can combine them together. This document
+focuses on the latter two options.
