We're developing an application using EMA. In Refresh and Status messages there is something like ClearCache and DoNotCache. What is meant by "cache"?
Suppose we are getting Market By Price data (market depth data) and we want to get and maintain a state of the order book. Then for every ADD, UPDATE or DELETE of prices we update our state of the order book. Then if there is a Msg with ClearCache, do we need to clear our total order book? Does cache means in this case our current state of the order book?
Can we have a batch request with EMA JAVA API (Version 22.214.171.124)? Also, Would be good to know how EMA handles batch internally and return response? Will it be a callback per RIC or single callback for whole batch.
