OPTIMAL QUERY SCHEDULING ACCORDING TO DATA FRESHNESS REQUIREMENTS
. . ABSTRACT OF THE DISCLOSURE A process for optimal query scheduling includes receiving in an information retrieval data processing system, a request to accelerate query execution of a specified query to a time prior to a scheduled time. A specific field corresponding to data in a database is then identified in the query and a freshness of data requirement for the specific field retrieved along with a frequency of change of the data corresponding to the specific field. Then, if execution of the specific query at the time prior to the scheduled time instead of the scheduled time is determined not to violate the freshness of data requirement based upon the frequency of change of the data corresponding of the specific field, the specific query is scheduled for execution at the time prior to the scheduled time. But otherwise, the scheduled time may be maintained for executing the specific query. CA 3069090 2020-01-21

LIVE MIGRATION OF CLUSTERS IN CONTAINERIZED ENVIRONMENTS
The technology provides for live migration from a first cluster to a second cluster. For instance, when requests to one or more cluster control planes are received, a predetermined fraction of the received requests may be allocated to a control plane of the second cluster, while a remaining fraction of the received requests may be allocated to a control plane of the first cluster. The predetermined fraction of requests are handled using the control plane of the second cluster.
