Hyracks Projects

• Histograms Computing histograms on hyracks data, ideally using sampling. The histogram representation can be similar to postgresql's histograms which are quite clean and simple.
• SQL window operators Implement some of the SQL window operators in Hyracks. The key issues here will be implementing them in parallel. Tuples may contribute to multiple windows, which may be in different nodes; you may have to route such tuples to all relevant nodes.
• HBase-Hyracks Integration Build Hyracks operators which can access data in HBase.
