2016 Proceedings of the 2016 International Conference on Management of Data - SIGMOD '16  
Instead of statically assigning query operators to heterogeneous processors, SABER employs a new adaptive heterogeneous lookahead scheduling strategy, which increases the share of queries executing on  ...  Such heterogeneous architectures have the potential to improve the performance of data-intensive stream processing applications, but they are not supported by current relational stream processing engines  ...  The hybrid stream processing model requires that each query can be scheduled on any heterogeneous processor, leaving the scheduling decision until runtime.  ...
