Query Timeouts
On this page
You can specify a timeout for read operations to complete. If a query exceeds the specified time limit, MongoDB stops the query and the query does not return any results.
To prevent ongoing queries from negatively impacting deployment performance for long periods of time, specify a suitable query timeout for your application.
For details on how MongoDB stops queries that exceed a specified timeout, see cursor.maxTimeMS Behaviors.
Specify a Time Limit for Queries
To specify a time limit for a query, perform one of these actions:
Specify the
maxTimeMS()option for a query. ThemaxTimeMSoption lets you specify a query timeout at the operation level, meaning you can specify different time limits for different queries.Specify a global default time limit for all queries. The
defaultMaxTimeMScluster parameter specifies a default time limit for individual read operations to complete, and applies to all queries that do not include themaxTimeMS()option. If a query specifies amaxTimeMS()option, that value overrides thedefaultMaxTimeMSvalue.
