Streaming, big data applications face challenges in creating scalable data flow pipelines, in which multiple data streams must be collected, stored, queried, and analyzed. These data sources are characterized by their volume (in terms of dataset size), velocity (in terms of data rates), and variety (in terms of fields and types). For many applications, distributed NoSQL databases are effective alternatives to traditional relational database management systems. This paper considers a cyber

We evaluate Accumulo's ingestion scalability as a function of number of client processes and servers. We also describe a flexible data model with effective techniques for query planning and query batching to deliver responsive results. Query performance is evaluated in terms of latency of the client receiving initial result sets. Accumulo performance is measured on a database of up to 8 nodes using real cyber data.
