Managing data dependencies among multiple jobs using separate tables that store job results and dependency satisfaction

摘要

Disclosed are various embodiments for the management of dependencies on data. Multiple jobs are executed in one or more computing devices. It is determined that a first one of the jobs consumes data produced by a second one of the jobs, and a dependency is recorded. It is then determined whether the dependency is satisfied. When the dependency is determined to be unsatisfied, execution of the first one of the jobs is suspended. When the second one of the jobs produces the data, the dependency is updated as being satisfied. Execution of the first one of the jobs is resumed in response to the dependency being updated as being satisfied.
