In CHI WriteNoSnp transaction, why DBID is required in COMP response from completer?

York Tsang 4 months ago

I think TxnID is enough for the requester to find out which request the COMP is corresponding to. Is DBID redundant here?

You're correct that the Requester can use the TxnID to establish which request the Comp message relates to. However, you can think about DBID as being the TxnID that the Home applies to the transaction...
