Kaminario K2 (discontinued) vs. Oracle Coherence

K2 works well in our mixed-use virtual environment. I would not hesitate to place any workload on K2, it has always performed well. We use fiber-channel connectivity as it replaced our large legacy storage array, replacing one rack of spinning disks with 4U of flash.

Oracle Coherence can be used to solve latency problems by caching data near the application tier. In-memory performance helps to reduce data contention, thus improving application response time. Oracle Coherence does a great job at scaling linearly and can do so dynamically. Oracle Coherence can replicate data so it can be part of a disaster recovery solution. One thing that is often overlooked with elastic caches is their ability to analyze data in memory, leveraging the processing power of the data grid. This is something Oracle Coherence does exceptionally well. Oracle Coherence also provided event handling capabilities to allow applications to respond to events triggered by transactions.

• Great performance
• Great support
• Super-simple to use

• Performance. Superfast resolution of complex data grid queries.
• Reliability. Availability domain support for disaster recovery.
• Programming model. Frictionless API for use with Java 8.

• Not well known, so third-party support is lacking
• Data reduction is good, but not as good as expected (actual 2.7:1)

• I can't really come up with too many flaws, but possibly a bit expensive considering there are good open source caches like Ehcache.

Oracle Coherence support team is responsive and knowledgeable. We contacted them to ask a couple of design questions about how we were setting up Oracle Coherence based on how we used IBM's Datapower Extreme Scale. They were able to guide us so that we got the design correct the first time and didn't have to go back and re-architect our design later.

We performed a bake-off with K2 and one other vendor and they performed identically. K2 pricing was aggressive, performance was great, and it offered the features that we needed at a price that we could afford

DataSynapse GridServer has the same cache functionality connected with a grid distributed application deployment platform. It provides all the necessary tools to configure and manage these applications. On the otherhand Oracle Coherence has more a flexible configuration and better performance. Also the Oracle configuration and monitoring tools are more convenient and informative than the DataSynapse ones.

• Installing K2 reduced runtime of one of our batch processes, freeing up one employee for other tasks.
• Less time managing storage.

• In my current project, it is yet to be decided as we are on the way to make it live for users. But I am sure it will be an added value to obtain timely calculations.
