Structured peer-to-peer overlay networks or Distributed Hash Tables (DHTs) are distributed systems optimized for storage and retrieval of read-only data. In this paper we elaborate...
For complex queries in parallel database systems, substantial amounts of data must be redistributed between operators executed on different processing nodes. Frequently, such inter...
Parallel database systems have to support the effective parallelization of complex queries in multi-user mode, i.e. in combination with inter-query/inter-transaction parallelism. ...
Traditional DHT (Distributed Hash Tables) abstraction distributes data items among peer nodes on a structured overlay network. This introduces a number of issues when nodes are un...
Recently, a number of papers have been published showing the benefits of column stores over row stores. However, the research comparing the two in an "apples-to-apples" ...
