I understand that a Channelset can be used to handle failover in EMA.
I was wondering, in the case of failover, will all open items (ie connections to stream market data) automatically reconnect?
If so, will the item/instrument handles change?
Hello @mzmuda33 ,
EMA implements "Single Open" approach. Please see EMA RDM Usage Guide -> Single Open for a description, upon the reconnect, EMA recovers open items, and they should have the same handles, so when the subscription is no longer needed, the consumer can unregister from the subscription.
Hi @mzmuda33,
No the item handle does not change when the failover happens. EMA will automatically subscribe to all the instruments on your behalf when using Channel Set.
