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.
