Abstract: Various technologies described herein pertain to controlling geo-scale analytics with bandwidth and regulatory constraints. An analytical query (e.g., a recurrent analytical query, a non-recurrent analytical query, etc.) to be executed over distributed data in data partitions stored in a plurality of data centers can be received. Moreover, a query execution plan for the analytical query can be generated, where the query execution plan includes tasks. Further, replication strategies for the data partitions can be determined. A replication strategy for a particular data partition can specify one or more data centers to which the particular data partition is to be replicated if the particular data partition is to be replicated. The tasks of the query execution plan for the analytical query can further be scheduled to the data centers based on the replication strategies for the data partitions. The analytical query can be part of a workload of analytical queries.

Abstract: One embodiment provides a method comprising storing a first set of explicitly enumerated data values in a first window data structure associated with a first time span. The method further comprises storing one or more sets of summary statistics in a second set of window data structures. Each window data structure of the second set of window data structures is associated with a time span older than the first time span. The one or more sets of summary statistics are based on a second set of data values. The method further comprises storing a third set of explicitly enumerated data values in a third set of window data structures, wherein each data value of the third set of explicitly enumerated data values is annotated.
