I have a Rest Based Java application which creates and gets data from SAP Gateway for sales order. The Order in SAP keeps updating with status of order such as dispatch/closed/canceled from messages.
The application is expected to be slow. Introducing coherence in java to SAP layer is expected to improve the performance but there is a risk that the data in coherence layer will be stale and so order data on UI will be old due to cached data.
