Distributed Search on Large NoSQL Databases

摘要

This work focuses on performance and scalability of different policies for solving queries on large noSQL databases with clusters. Distribution of data and queries are amongst the main problems, given the distributed nature of clusters: basically a set of networked computers. The basic centralized model (for both, data and processing) is used as a departure point and different distributed configurations are experimented with, in order to determine several guidelines for performance improvement. Apache Solr has been used for database management and search server. The current contents of the Wikipedia in Spanish (with about 4.5 GB) have been used as an example of a NoSQL database for experimentation.
