WitrynaYou can set the colormap for an image, pcolor, scatter, etc, using a keyword argument:: imshow (X, cmap=cm.hot) or using the :func:`set_cmap` function:: imshow (X) pyplot.set_cmap ('hot') pyplot.set_cmap ('jet') In interactive mode, :func:`set_cmap` will update the colormap post-hoc, allowing you to see which one works best for your data. Witryna根据cap理论，一致性(c)，可用性(a)，分区容错性(p)，三者不可兼得，必须有所取舍。而传统数据库保证了强一致性(acid模型)和高可用性，所以要想实现一个分布式数据库集群非常困难，这也解释了为什么数据库的扩展能力十分有限。
