Innesto: A Searchable Key/Value Store for Highly Dimensional Data

Key/value data storage systems serve as the fundamental component of scalable cloud-based services. However, the scalability of existing key/value data stores comes at the cost of a narrow data access API. We present Innesto, a distributed key/value data store that provides search as part of its API. Search allows data items to be retrieved based on constraints on multiple different attributes. Innesto´s strong consistency data model and its transactional interface bring much of the power of traditional relational databases to cloud-scale performance. Our evaluation of Innesto shows it offers these extra features with competitive performance compared to an industrial key/value data store such as Cassandra which offers an inferior feature set.
