One or more computing devices, systems, and/or methods for automated materialized view table generation and maintenance are provided. A log, comprising queries and latencies of processing the queries, is evaluated to identify a list of combinations of fields that occur greater than a threshold frequency and/or occur in queries having latencies greater than a threshold latency. A materialized view generation script is executed against a main database to generate a materialized view table associated with a combination of one or more fields from the list. A middleware component is configured to selectively direct a query to the main database or to the materialized view table based upon whether the materialized view table comprises preliminary query results for fields specified by the query.

Automated materialized view table generation and maintenance

Technologies for enhancing work scheduling of a big data framework. The technologies can include generating, in a database, configurable namespaces to be used by a work scheduling enhancement application to group together tasks of one or more big data clusters. The namespaces can be hierarchical. The technologies can also include linking in the database, by the application, related tasks with respective namespaces to categorize and group together the related tasks. The technologies can also include configuring, by the application, a display scheme for displaying error handling and root cause analysis of tasks of the one or more big data clusters. The technologies can also include generating or rendering, by the application, a GUI having a navigable hierarchal view for displaying the namespaces. The generation or rendering of the GUI can be based partially on the display scheme.
