Optimizations are provided for interconnecting event sources with event subscribers in a seamless manner so that the native formatting/schema methodologies used by event sources and subscribers will not need to be natively modified. An event grid service is provided as a routing and mapping service. This event grid service receives event data that may be organized in any kind of format. By analyzing the format, the event grid service determines whether the format correlates with a format used by a consumer of that event data. If the formats conform, then the event grid service extracts relevant data from the event data and pushes it to the subscriber. If the formats do not conform, the event grid service intelligently generates a mapping to map the two formats together.
