This paper studies the system performance of SQL-on-Hadoop technology and MPP technology in an OLAP and OLTP mixed scenario, which is becoming the most common big data application scenario in telecom industry. Until recently, most SQL-on-Hadoop systems only focus on the speed of data analysis but overlook the support for transactions. MPP columnar databases, on the other hand, are able to deal with...
Mobility load balancing (MLB) is widely used to address the uneven load distribution problem. The basic idea is that a hot-spot cell selects less-loaded neighbouring cells as assistant cells, and thenshiftsitsedge users to assistant cells via the handover region adjustment. However, shifted users receive the reduced signal power after MLB, which may result in the poor link quality problem for shifted...
