NoSQL data stores are becoming increasingly popular in application development. These systems are attractive for developers due to their ability to handle large volumes of data, as well as data with a high degree of structural variety. Typically, NoSQL data stores are accessed programmatically. Due to the imminent lack ...

Although most NoSQL Data Stores are schema-less, information on the structural properties of the persisted data is nevertheless essential during application development. Otherwise, accessing the data becomes simply impractical. In this paper, we introduce an algorithm for schema extraction that is operating outside of ...

We demonstrate AutoShard, a ready-to-use object mapper for Java applications running against NoSQL data stores. AutoShard's unique feature is its capability to gracefully shard hot spot data objects that are suffering under concurrent writes. By sharding data on the level of the logical schema, scalability bottlenecks ...

Schema-less NoSQL data stores offer great flexibility in application development, particularly in the early stages of software design. Yet over time, software engineers struggle with the heavy burden of dealing with increasingly heterogeneous data. In this demo we present Cleager, a framework for eagerly managing schema ...
