US Patent 9870269 Job allocation in a clustered environment

Described herein are systems, devices, and methods for using a job scheduler that allocates jobs to cluster nodes in a data warehouse. The cluster nodes in the data warehouse may generate information about the availability to execute new jobs. The job scheduler may use the information about the availability to determine which cluster node to allocate a particular job based on current information or a prediction of availability. As a result the data warehouse becomes more stable.
