Multi Tenancy for Cloud-Based In-Memory Column Databases: Workload Management and Data Placement

With the proliferation of Software-as-a-Service (SaaS) choices, it's turning into more and more very important for person SaaS companies to function their companies at a low-budget. This booklet investigates SaaS from the point of view of the supplier and exhibits how operational charges could be lowered by utilizing “multi tenancy,” a strategy for consolidating a number of shoppers onto a small variety of servers.

Example text

Consider the following two Boolean expressions: E1 = a1 ∧ a2 ∧ ··· ∧ ap ∧ ¬b1 ∧ ¬b2 ∧ ··· ∧ ¬bq and E2 = a1 ∧ a2 ∧ ··· ∧ ap ∧ ¬b1 ∧ ¬ b2 ∧ ··· ∧ ¬bq ∧ ¬c1 ∧ ¬c2 ∧ ··· ∧ ¬cr. The Boolean expressions E1 and E2 correspond to conditional patterns 〈Y, Xk〉 and 〈Y, Xk+1〉, respectively. The expression E2 is more restrictive than the expression E1. Thus, supp(E1, D) ≥ supp(E2, D). 1, let Y = b, X1 = {a, b} and X2 = {a, b, c}. 2. We observe that supp〈Y, X1, D〉 ≥ supp〈Y, X2, D〉. 4 Mining Conditional Patterns For mining conditional patterns in a database, we need to find their conditional supports.

1(e) contains the set of transactions containing the items b and c, but not the item a with respect to {a, b, c}. Thus, it corresponds to the pattern itemset of 〈b ∧ c, a ∧ b ∧ c〉. The shaded region in Fig. 1(f) contains the set of transactions containing the item b, but not the items a and c with respect to {a, b, c}. Thus, it corresponds to the pattern itemset of 〈b, a ∧ b ∧ c〉. Finally, the shaded region in Fig. 1(g) contains the set of transactions containing the item c, but not the items a and b with respect to {a, b, c}.
