Seconds_behind_master是我们观察主从延迟的一个重要指标。但任何指标所能表示的精度都是有限的。例如用精度只能到秒的指标去衡量毫秒级的表现就会产生非常大的误差。如果再以此误差去分析问题，就会让思维走上弯路。例如用Seconds_behind_master去评估1s内的主从延迟就是一个典型的例子。
Matplotlib是Python中令人惊叹的可视化库,用于数组的二维图。 Matplotlib是一个基于NumPy数组的多平台数据可视化库,旨在与更广泛的SciPy堆栈配合使用。 matplotlib.colors.LinearSegmentedColarmap matplotlib.colors.LinearSegmentedColarmap类属于matplotlib.colors模块。 matplotlib.colors模块用于将颜色或数字参数转换为RGBA或RGB。

In this section we present a pedagogic example showing how the PyLops library can be used to frame and solve an interpolation problem by using linear operators. More specifically, we aim at interpolating onto a regular grid a one dimensional signal composed of three sinusoids that has been sample...
