We are using RFA 8.1 C++ api to consume Level2 market data using MBP and MBO domain. I have below questions -
1. Is it possible that Update(not Refresh) response message be divided into multiple response messages? If YES then how do I supposed to know which is first and last part of it? Is there Something similar to SnapshotCompleteFlag to indicate this is last update message?
2. Is it possible to know number of map entries present in map before iterating over it? I know there is something called TotalCountHint but I suppose it is not present always? Is it correct?
