Add an input sampling strategy（添加输入采样策略）

If your input datasets are large, you can speed up preview times by adding a sampling strategy to those inputs.

1. Right-click the input node that you would like to sample, then select Sampling strategies in the dropdown menu.

1. From the sampling strategies dialog, select the desired input dataset.

1. Choose the Percentage strategy, and enter a number between 1 and 100 to downsample your input.

1. Close the dialog. A blue badge should now appear on the top right of your input node, indicating that a sampling strategy has been applied.

The preview panel of any nodes downstream of the input will also indicate that sampling was applied.

添加输入采样策略

如果您的输入数据集较大，可以通过为这些输入添加采样策略来加快预览速度。

1. 右键单击您想要采样的输入节点，然后在下拉菜单中选择采样策略(Sampling strategies)。

1. 在采样策略对话框中，选择所需的输入数据集。

1. 选择百分比(Percentage)策略，然后输入1到100之间的数字来对输入进行降采样。

1. 关闭对话框。此时输入节点的右上角应出现一个蓝色徽章，表示已应用采样策略。

输入节点下游的任何节点的预览面板也会显示已应用采样。
