How do you handle live traffic and serve correct results while switching databases? In this talk, Vilde will share a general step-by-step approach to live database migrations from a backend application developer perspective. Using two recent migrations as examples she will walk through what went wrong, what went right, the patterns such projects follow, and how you can apply this to your own projects. You will hear about a database migration from MySQL to Cassandra in a high-traffic critical production system and a data migration that involved recreating the whole database in a complex legacy system.
Vilde Opsal is a feminist developer from Norway, currently living in Berlin by way of California.
