Container for the parameters to the CheckpointDurableExecution operation. Saves the progress of a durable function execution during runtime. This API is used by the Lambda durable functions SDK to checkpoint completed steps and schedule asynchronous operations. You typically don't need to call this API directly as the SDK handles checkpointing automatically.
Each checkpoint operation consumes the current checkpoint token and returns a new one for the next checkpoint. This ensures that checkpoints are applied in the correct order and prevents duplicate or out-of-order state updates.

Properties
| Name | Type | Description | |
|---|---|---|---|
|
|
CheckpointToken | System.String |
Gets and sets the property CheckpointToken. A unique token that identifies the current checkpoint state. This token is provided by the Lambda runtime and must be used to ensure checkpoints are applied in the correct order. Each checkpoint operation consumes this token and returns a new one. |
|
|
ClientToken | System.String |
Gets and sets the property ClientToken. An optional idempotency token to ensure that duplicate checkpoint requests are handled correctly. If provided, Lambda uses this token to detect and handle duplicate requests within a 15-minute window. |
|
|
DurableExecutionArn | System.String |
Gets and sets the property DurableExecutionArn. The Amazon Resource Name (ARN) of the durable execution. |
|
|
Updates | System.Collections.Generic.List<Amazon.Lambda.Model.OperationUpdate> |
Gets and sets the property Updates. An array of state updates to apply during this checkpoint. Each update represents a change to the execution state, such as completing a step, starting a callback, or scheduling a timer. Updates are applied atomically as part of the checkpoint operation. |
