The data in this instance is transient; no backup or replication will be required.

D. sync_binlog=0: This disables the synchronizing of the binary log to disk after every commit. This can reduce disk I/O, but it comes with a risk of losing transactions in case of a crash. Since your data is transient, this might be an acceptable risk. E. innodb_doublewrite=0: Disabling innodb_doublewrite can reduce disk I/O, but it comes with a risk of data corruption in the event of a crash. Since your data is transient and doesn’t require backup or replication, this might be an acceptable risk. G. innodb_undo_directory=/dev/shm: Moving the innodb_undo_directory to a memory-based filesystem like /dev/shm can reduce disk I/O and improve performance. However, this comes with a risk of running out of space for undo logs if the system has a high rate of updates/deletes/inserts.
