You have semi-synchronous replication configured and working with one slave. rpl_semi_sync_master_timeout has never been reached.
You find that the disk system on the master has failed and as a result, the data on the master is completely unrecoverable.
Which two statements are true? (Choose two.)
- A.No committed transactions are lost.
- B.The slave automatically identifies that the master is unreachable and performs any required actions so that applications can start using the slave as the new master.
- C.As soon as the incident happens, application can read data from the slave and rely on it to return a full and current set of data.
- D.Reads from the slave can return outdated data until the value of the rpi_semi_sync_master_timeout variable is reached.
- E.Reads from the slave can return outdated data for some time, until it applies all transactions from its relay log.
- F.A small amount of committed transactions may be lost in case they were committed just before the disk failure.
