This service optimizes requests from the client working places to DB in order to eliminate peak loads on the server, in particular, it is used for getting information about changes happened with MDB and passing this information to working DIGISPOT II applications. Using of mdb_modify is mandatory if quantity of simultaneously working DIGISPOT II applications (DJin, BCS Editor, etc) exceeds 20. This service is included in the MDB Advanced Engine (DS-29-000-15) and is not included in the MDB Engine (DS-07-000-15).
All working places periodically are sending requests for getting new information from DB. If this service is not used, SQL-server will be overloaded by these multiple similar requests for updates which will be processed by server in turn. At using the service mdb_modify, all requests from all clients are "grouped" in the application and a single request is sent to the server. The data being received are stored in the files which are read by all open applications in parallel. This service helps to fantastically lower the load on the server and to provide simultaneous work of a big number of clients with the server. Practically, we have checked that the server can work with 1000 clients simultaneously.
