 A Batch Query enables you to request queries with long-running CPU processing times. Typically, these kind of requests raise timeout errors when using the SQL API. In order to avoid timeouts, you can use Batch Queries to [create](#create-a-job), [read](#read-a-job) and [cancel](#cancel-a-job) queries. You can also run a [chained batch query](#chaining-batch-queries) to chain several SQL queries into one job. A Batch Query schedules the incoming jobs and allows you to request the job status for each query.
