It's quite possible you're using the wrong tool for the job. Since this

using another database such as PostgreSQL or Oracle. Alternatively,
consider the option of re-architecting the application to distribute the

The database does write the data to disk when an UPDATE or INSERT is
sent, but not synchronously. (IOW, it doesn't call fsync() after each
write.) So there is no guarantee that the data will be in the tables
