This talk will firstly cover standard data-storage migration approaches for the microservices and the challenges you’ll be faced with using/implementing them. After that, we will talk about event-driven design pattern (microservices local state) that enables simple storage/schema migration. At Playtika our latest use-case was migration for at least 100 microservices from Couchbase to Aerospike, under the hood we used Spring Data project. Combining of the 2 approaches enables you fast, reliable and head-ache free migrations.
