Redis

Top Pro

Open-source

It's licensed under the BSD license. See More

Top Con

Takes careful setup to have it work as a reliable DB

Redis is mainly built as an in-memory cache. Data integrity is not a primary concern and neither is persistance. See More

Top Pro

May be used alongside any other DB

Top Con

API retranslation

Redis API will be different from other persistent DB you'll use, so you will have to retranslate queries to use both. See More

Top Pro

Follows Separation of Concerns

Use Redis in role of event hub decoupled from storage entity. See More

Top Con

Misses features present in other DBs

Some geo features (nearest search, GEORADIUS) are not available in stable versions. See More

Top Pro

There are numerous client libraries and frameworks to make redis more powerful

For Node.JS for example you can get something similar to what Parse.com was offering by using Node ORM. See More

Top Pro

Good support

Redis has great docs, an active mailing list, and a github community. See More

Top Pro

Redis is written in ANSI C and therefore doesn't have a VM
