Question
You are a BigQuery admin supporting a team of data consumers who run ad hoc queries and downstream reporting in tools such as Looker. All data and users are combined under a single organizational project. You recently noticed some slowness in query results and want to troubleshoot where the slowdowns are occurring. You think that there might be some job queuing or slot contention occurring as users run jobs, which slows down access to results. You need to investigate the query job information and determine where performance is being affected. What should you do?
Options
- AUse slot reservations for your project to ensure that you have enough query processing capacity and are able to allocate available slots to the slower queries.
- BUse Cloud Monitoring to view BigQuery metrics and set up alerts that let you know when a certain percentage of slots were used.
