In the last decade, key-value data storage systems have gained significantly more interest from academia and industry. These systems face numerous challenges concerning storage space- and read optimization. There exists a large potential for improving current solutions by introducing new management techniques and algorithms. In this paper we give an overview of the basic concept of key-value data storage systems and provide an explanation for bottlenecks. Further we introduce two new memory management algorithms and a improved index structure. Finally, these solutions are compared to each other and discussed.
