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.
For .NET Core this operation is only available in asynchronous form. Please refer to CheckpointDurableExecutionAsync.
