Abstract: A system and method for identifying whether data skew is causing delays in a map phase and/or a reduce phase of a query of a distributed database. The system and method identify the values of various metrics relating to a database query. These metrics include map phase and reduce phase durations and various related metrics. The system and method gather statistics of multiple queries to determine correlation levels between the metrics and the map phase and reduce phase durations. Based on the statistics, the system and method determine whether one or both of the map and reduce phases for a query/response are taking longer than expected. If the durations are longer than expected, the system identifies the delay as caused by data skew and informs the originator of the query.

Abstract: A computer-implemented method includes detecting a first user is editing a first version of a content piece. A first feature set value is determined, describing a first set of values of one or more features of the first version. Based on the first feature set value, a first maturity score of the first version is determined, using a mapping. It is detected that a second user is editing a second version of the content piece in parallel with the first user editing the first version. A second feature set value is determined, describing a second set of values of the one or more features of the second version of the content piece. Based on the second feature set value, a second maturity score of the second version is determined, using the mapping. It is detected that the second maturity score meets a maturity threshold. Thus, a remedial action is performed.
