Опыт плавной миграции высоконагруженного проекта (20+ млн. пользователей) c MySQL на PostgreSQL
A brief story how MySQL → PG migration could increase company efficiency tenfold times:
- Program code has been reduced 50 times, with optimization of backend team (from 15 to 3 engineers)
- Software development of new features has become measuring in days, not in months
- Infrastructure costs per 1M users have been reduced 20 times
- Database structure and technical documentation were simplified significantly, from 100K high-dependent tables to just 20 simple tables
- New security level because of total forbidden on external SQL commands to the database
- Quick analytics aggregation on multiple parameters, without external analytics systems
- The last, but not the least: the main business was keeping alive during migration
