The Computer Wants to Lose Your Data

Conference
Schedule
·SRECon25 Europe

Join PlanetScale's Chris Sinjakli at SRECon25 Europe for a deep dive into the surprising ways that computers can fail to save or corrupt our data.

This technical talk will explore the intricate challenges of data storage reliability, examining:

  • MySQL's doublewrite buffer - Understanding this critical mechanism for data integrity
  • Postgres fsync syscall challenges - The complexities of ensuring data persistence
  • Write-through disk caches - How caching can impact data reliability
  • Database replication limitations - Why replication isn't always the safety net we expect

Through real-world examples and technical deep-dives, Chris will reveal the hidden vulnerabilities in our data storage systems and the engineering solutions that help protect against data loss.
