This plugin can be used to filter incoming requests from the SDKs that match criteria you define.
You can create high-level filtering rules, such as ignoring all data coming from a certain country or IP address. It is also possible to filter data on a session or event level of granularity both with optional segmentation criteria, such as ignoring all "Contact" events if there is a segmentation property A equals to B or ignoring all sessions originating from an application version 0.9.
