I am using ETA Value Added service with watchlist enabled, I am looking into VAConsumer for reference.
I want to use cache, so that incoming message will be applied to cache and there will be another thread reading from cache.
But is there any way while reading from cache, which will return only updated fields?
For eg. ASK and BID are stored in cache and other thread also reads it from cache. but next time only BID is changed and I want to read and send only BID message to the application for processing as our application is expecting only delta.
