Re: Consistency problem in daos

Lombardi, Johann

Hi there,


If abort is called either by the application directly (daos_tx_abort()) or by DAOS internally (something went wrong during commit), then all changes associated with the transaction are discarded and consistency is preserved. None of the uncommitted modifications are visible to external readers.

Subject: [daos] Consistency problem in daos


1. Will abort be triggered if a transaction fails in the commit phase in Daos? (I read the code myself and found that this happens when the submission fails. At this time, some nodes may submit successfully)
2. If abort is triggered, what is the meaning? Will strong consistency be lost?
