In this chapter we start by presenting some key results concerning the number of ordered k-partitions of multisets with equal sums. For these we give generating functions, recurrences and numerical examples. The coefficients arising from these formulae are then linked to certain elliptic and super...

In this article, we first state some relations about the number of partitions of a set under some particular conditions and then we give a new relation about the number of partitions of an n-set, i.e., Bell number B(n). Finally, we give some formulas to count partitions of a natural...

On the Number of Partitions of a Sample into Groups for the Stability CriterionstabilitycriterionclassificationpartitioningA new approach to solution of the problem of grouping of objects based on the stability criterion is presented. The stability is defined by the index of structural disposition of ...

A relationship between linear partitions and minimal pairs of a finite point set in the plane was established in [2]. This relationship is used here for counting the number of linear partitions of the set of points of the ( m, n )-grid, a rectangular part of the infinite grid. In orde...
默认的 Spark SQL 会使用spark.sql.shuffle.partitions的数量来进行aggregation和join,默认值为 200。这会导致 partition 膨胀的问题,200个 partition 都需要执行,无论大小,尽管有些 partition 是没有数据的。 Case 1: Default Number of Partitions — spark.sql.shuffle.partitions Property ...
The number of topics is related to the total number of topic partitions and the number of partitions in each topic. There is an upper limit on the aggregate number of par
