User Domenico has asked us the following question:
could you please confirm the limit of maps one can upload in a specific workspace?
Survey Solutions does not directly limit the number of maps that can be uploaded to a workspace. (Declared limits are listed in the Survey Solutions Limits). That said [as anything in the computers world] every server’s and mobile device’s storage capacity is limited, thus it will be exhausted at some point.
The real binding constraint that is experienced much more often is the limit on the individual map size and uploaded archive size (both listed in the above table).
Additionally, sending hundreds or thousands of maps to an enumerator makes their work difficult when it comes to maps selection - scrolling long lists of available maps is a tedious task and is subject to a human error (clicking the wrong map with a similar name/number). Instead, it is best to provide the interviewers with a limited set of map files that are needed for their immediate tasks (e.g. in the current district where they are working). Map assignments can be revised later, to replace the older maps with ones that are needed for upcoming areas.
Having a very large number of maps and a very large number of users may cause some functionality crippling. Specifically, the matrix of maps assignments can be generated too slowly, so that a timeout is experienced by the client side. The number of cells in that matrix has reached billions (if memory serves me well), but of course the exact values would depend on the performance of the server/DB and other factors, so it is not a hard limit. Notably, managing maps through API requests remained a speedy and feasible way in that case since it doesn’t involve constructing the maps assignment matrix.
