> You may find a a bit more what's behind the demo... That only says "the engine is a Java-based proprietary solution which was about 20x faster than comparable implementations in Coherence, Ignite or Hazelcast. (Yes, we tested it.)". So, comparable to those. Some sort of Java friendly in-memory cache. Perhaps, for this specific kind of data (dates/location/room-type/price/availability), you've figured out an optimal storage/retrieval layout that's fast. That seems plausible. What doesn't seem plausible is that your cache is generally 20x faster than every other cache in the space.
