This article details Salesforce's successful migration of its Marketing Cloud caching infrastructure from Memcached to Redis. The team achieved this transition without downtime, handling 1.5 million cache events per second while ensuring application performance and data integrity. It highlights the challenges faced and strategies employed during the migration process.

Redis has released version 8.2, which returns to being free and open-source software (FOSS) under the GNU AGPL license, featuring significant performance enhancements. Meanwhile, the older FOSS version 7.2 is approaching its end of life, prompting users to consider migration to either Redis 8.2 or the forked Valkey project. Redis 8.2 boasts improvements such as faster command execution and reduced memory usage.
