Likelihood to Recommend Real-time transaction processing (both reads and writes) is where DataStax Enterprise shines. It's very fast with linear scalability should more resources be needed. Additional nodes are added very easily. DataStax Enterprise on its own (without Solr or Spark enabled) isn't well suited for long complicated reports. The data model doesn't support joining multiple tables together which is common in BI reporting.
Read full review If you're a.NET developer searching for a system other than SQL Server for business assessment, then you must try RavenDB. RavenDB is a fantastic document-oriented system that has been specifically developed to work with all.NET or Windows systems. Developers are continually working on such systems to eliminate their flaws while also providing a few benefits. We must refresh ourselves on a regular basis since the free software system is like an open area where anybody may stand up with a brilliant solution to the issue. RavenDB is absolutely worth a look
Read full review Pros Datastax Cassandra provides high availability and good performance for a database. It is built on top of open source Apache Cassandra so you can always somewhat understand the internal functioning and why. Datastax Cassandra is fairly simple to start using, you can install/setup your cluster and be productive in 1 day. Datastax Cassandra provides a lot of good detailed documentation, and when starting, the detailed free videos on the Datastax site and documentation are very helpful. Datastax Enterprise Edition of Cassandra provides more tools, good support, and quick response SLA for enterprise business support. Read full review Document Database - no Object-Relational Impedance Mismatch ACID support that is optimized for performance Can be easily integrated into automated tests (unit tests) Easily configurable via C# code Comes directly with RavenStudio - no SSMS or SQL Developer required In general low footprint when it comes to memory and disk consumption Useful safety nets for new developers - e.g. by default an exception is thrown when you make too many requests within a session Read full review Cons Cassandra is a bit difficult to learn and understand The costs are slightly higher for our company Hardware requirement is moderate to high at the beginning Read full review The documentation is very good, but it's sometimes hard to find the topic I'm looking for. Updating references is done manually. It would be nice if there was a feature to help with that. I'm not sure that's even possible though. Read full review Likelihood to Renew We will continue to use it because it scales well with commodity hardware and we are satisfied with the documentation and support.
Read full review We've had an excellent experience using RavenDB. Internally we are testing the newer features in 5.0 such as time series, which will effect the con specified previously dependent on the real world performance. We foresee that BattleCrate will continue to use RavenDB as we grow.
Read full review Usability There is a bit of a learning curve and tasks that are simple in traditional RDBMS systems can be complicated with DataStax Enterprise but once you get the hang of denormalizing data and getting the data model correct DataStax Enterprise is very usable. Usability from the developer's standpoint is very simple - the complication is on the architecture side with the data model.
Read full review Really good .NET client that is very easy to use. The management studio is excellent and puts anything that Microsoft or Oracle have to shame. Very quick to develop with once the complexity hurdle has been overcome. Initially using it can be a bit painful until you fully grasp the event sourced nature of the indexing.
Read full review Support Rating DataStax has the best community. They have instant customer support to solve problems and are knowledgeable of the problems faced by the customer. The documentation is pretty top-notch.
Read full review The support is really fast and flexible. Since one single working day, we got a response to our first request, only 4 days later we got a technical demonstration for our complete developer team to get in touch with raven and its performance. Also during our development, we got a quick response to questions.

Read full review Alternatives Considered DataStax Enterprise offered best-in-class write performance and scalability. The customer support team was very helpful in the adoption of new technology.
Read full review The given alternatives are also powerful and really good noSQL databases but the highest availability of RavenDB allows me/us to know it a lot better. RavenDB is encrypted by default wherever we use it in production and it has a high level of documents compression.
Read full review Return on Investment Highly Scalable Database, Highly Available Services, and Platforms. High Performance, Low Latency and Highest throughput across varying workloads. Configured, Tuned and Monitored correctly works to provide the best user experience! Negative: Maintenance and Debugging Corner Cases Read full review RavenDB has saved my customers a lot of money with their cloud services' tiered model. The database is able to grow with the project/company and can start out small at a low cost. RavenDB is free for three nodes and three CPUs, which makes it great for development scenarios. You're able to start rapidly building applications without having to worry about licensing. Scaling out has allowed us to use three small cloud servers when starting out and get the performance and throughput of a single larger server. Read full review ScreenShots
