Apache CouchDB vs. Percona Server for MySQL

Great for REST API development, if you want a small, fast server that will send and receive JSON structures, CouchDB is hard to beat. Not great for enterprise-level relational database querying (no kidding). While by definition, document-oriented databases are not relational, porting or migrating from relational, and using CouchDB as a backend is probably not a wise move as it's reliable, but It may not always be highly available.

Percona Server for MySQL covers 100% of our requirements in terms of our OLTP traffic and provides the High Availability levels required through a typical primary and 2 replica's using semi-synchronous replication. We're able to scale our writes using sharding, but a true distributed database would be a great option on top of this. In terms of OLAP traffic, we leverage columns stores available, but Percona Server fairs well

• It can replicate and sync with web browsers via PouchDB. This lets you keep a synced copy of your database on the client-side, which offers much faster data access than continuous HTTP requests would allow, and enables offline usage.
• Simple Map/Reduce support. The M/R system lets you process terabytes of documents in parallel, save the results, and only need to reprocess documents that have changed on subsequent updates. While not as powerful as Hadoop, it is an easy to use query system that's hard to screw up.
• Sharding and Clustering support. As of CouchDB 2.0, it supports clustering and sharding of documents between instances without needing a load balancer to determine where requests should go.
• Master to Master replication lets you clone, continuously backup, and listen for changes through the replication protocol, even over unreliable WAN links.

• Faster than other server solutions
• Installation and configuration process is easy from the user's standpoint
• Easy to learn and good support

• NoSQL DB can become a challenge for seasoned RDBMS users.
• The map-reduce paradigm can be very demanding for first-time users.
• JSON format documents with Key-Value pairs are somewhat verbose and consume more storage.

• Better documentation
• A better UI

Because our current solution S3 is working great and CouchDB was a nightmare. The worst is that at first, it seemed fine until we filled it with tons of data and then started to create views and actually delete.

Couchdb is very simple to use and the features are also reduced but well implemented. In order to use it the way its designed, the ui is adequate and easy. Of course, there are some other task that can't be performed through the admin ui but the minimalistic design allows you to use external libraries to develop custom scripts

It is easy to install and use. Using it along with Percona Monitoring and Management makes it even easier to use.

We are using opensource so we have not used customer support.

it support is minimal also hw requirements. Also for development, we can have databases replicated everywhere and the replication is automagical. once you set up the security and the rules for replication, you are ready to go. The absence of a model let you build your app the way you want it

It has been 5+ years since we chose CouchDB. We looked an MongoDB, Cassandra, and probably some others. At the end of the day, the performance, power potential, and simplicity of CouchDB made it a simple choice for our needs. No one should use just because we did. As I said early, make sure you understand your problems, and find the right solution.

Performance and stability sets Percona Server for MySQL apart from the rest. Percona embraces the upstream version and contributes towards the upstream version making MySQL stronger on two fronts and thus having a much larger community. Many quality contributions have been made by Percona into the base code. Percona provides great tools to support Percona Server for MySQL and this makes the monitoring and management easier

• It has saved us hours and hours of coding.
• It is has taught us a new way to look at things.
• It has taught us patience as the first few weeks with CouchDB were not pleasant. It was not easy to pick up like MongoDB.

• At the performance level, it maintains and even improves other open-source databases such as MariaDB or some commercial ones such as Oracle.
• If we compare it with MySQL, we could have up to 50% improvement in performance.
• For some small companies or startups, the price of the complete solution and the support can be a bit high.
