Splitting Large Matrices

The calculation of a large matrix of routes summaries can take up to several hours. If you request a large matrix, the calculation of the matrix may be canceled before the response is ready as the process may timeout. To avoid this issue, the resource has some matrix size limitations. Large matrices that exceed these limits must be split into smaller parts. Additionally, splitting one request into more, less demanding, requests makes it easier to monitor the progress of the overall calculation of the entire matrix. For more information on the limitations, see Calculate Matrix.
