Concrete data types for raw data organized in one or more columns of one or more tables may be determined. Functional data types for the one or more columns may be determined based on the raw data and the concrete data types such that a portion of the one or more columns may be associated with an identifier data type. Relationships between the one or more tables may be determined based on the portion of the one or more columns associated with the identifier data type. A schema representing the… Show more

A system for resolving interference on a cluster computing system includes a processor. The processor is configured to determine whether a second worker system has resources available to run the first or second task; in response to determining that the second worker system has the resources available to run the second task, move the second task from the first to the second worker system; in response to determining that the second worker system has the resources available to run the first task… Show more

A system for managing a cluster computing system includes a storage system and a processor. The storage system is configured to store a resource usage history for a set of tasks running on a computer cluster comprising a plurality of worker systems. The processor is configured to determine a required resource size for a task of the set of tasks based at least in part on the resource usage history for the task; resize resources allocated to the task to the required resource size; arrange tasks… Show more
