1. What would you like to communicate to the user about this feature? V2 has removed operation-specific timeout options. Instead, users should time out operations using either the client-level operation timeout defined by ClientOptions.Timeout or by setting a deadline on the context object passed to an operation. The following fields and methods have been removed: AggregateOptions.MaxTime and AggregateOptions.SetMaxTime ClientOptions.SocketTimeout and ClientOptions.SetSocketTimeout CountOptions.MaxTime and CountOptions.SetMaxTime DistinctOptions.MaxTime and DistinctOptions.SetMaxTime EstimatedDocumentCountOptions.MaxTime and EstimatedDocumentCountOptions.SetMaxTime FindOptions.MaxTime and FindOptions.SetMaxTime FindOneOptions.MaxTime and FindOneOptions.SetMaxTime FindOneAndReplaceOptions.MaxTime and FindOneAndReplaceOptions.SetMaxTime FindOneAndUpdateOptions.MaxTime and FindOneAndUpdateOptions.SetMaxTime GridFSFindOptions.MaxTime and GridFSFindOptions.SetMaxTime CreateIndexesOptions.MaxTime and CreateIndexesOptions.SetMaxTime DropIndexesOptions.MaxTime and DropIndexesOptions.SetMaxTime ListIndexesOptions.MaxTime and ListIndexesOptions.SetMaxTime SessionOptions.DefaultMaxCommitTime and SessionOptions.SetDefaultMaxCommitTime TransactionOptions.MaxCommitTime and TransactionOptions.SetMaxCommitTime This example illustrates how to define an operation-level timeout using V2, without loss of generality. // V1 findOneOpts := options.FindOne().SetMaxTime(1 * time.Second) res := coll.FindOne(context.TODO(), bson.D{{ "age" , 25}}, findOneOpts) if err := res.Err(); err != nil { log.Fatalf( "failed to run find command: %v" , err) } // V2 ctx, cancel := context.WithTimeout(context.TODO(), time.Second) defer cancel() res := coll.FindOne(ctx, bson.D{{ "age" , 25}}) if err := res.Err(); err != nil { log.Fatalf( "failed to run find command: %v" , err) } Similarly, WTimeout field has been removed from the WriteConcern struct. Instead, users should define a timeout at the operation-level using a context object. 2. Would you like the user to see examples of the syntax and/or executable code and its output? New examples are not required, but existing examples that apply setting a timeout using options need to be updated to set a timeout using a context. 3. Which versions of the driver/connector does this apply to? v2
