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.
