Abstract

[As shown in Fig. 8.3 in the previous chapter, the size of a RAMCloud Cluster can be changed without an interruption of the query processing executed by AnalyticsDB. However, the dynamic resizing in Fig. 8.3b is done via a purposeful revocation of a node which gives RAMCloud the time to redistribute the data from the to-be-removed node before its actual revocation. This kind of awareness cannot be expected in the event of a hardware failure. For the scenario of an unexpected hardware failure, RAMCloud features a fast crash recovery mechanism [ORS+\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${^+}$$\end{document}11] as explained in Sect. 3.3.]
