Problem with DISTINCT subscription and very high frequency updates
Hi all,
I have an item that represents the trades/transactions of a stock item. It is subscribed as DISTINCT in order to get the transactions one by one in detail. The adapter sometimes produces very high frequency update for such item (the meta adapter specifies 20 items/sec as a value for the MaxFrequency parameter but the adapter sometimes produces 100-200 items/sec for this item).
The problem is that the client perceives a very high delay because the server delivers max 20 items/sec (as expected) but does it discard intermediate items in order to privilege most recent updates.
How to improve this without increasing MaxFrequency/Bandwidth ?
Thanks
A
