Will using IMDG on top of NoSql really boost the performance of the application?

Does using a IMDG layer (Gemfire, HazelCast) on top of the NoSql db (MongoDB) improve the performance and scaleability of the application?

Maybe. As always, "It Depends".

On what? Primarily the characteristics of your data and your data access patterns. A few considerations (of many!) might be:

  • How much data do you have, and is it feasible and/or cost-effective to even attempt to cache a portion of it in memory?

    • Are there "hot" subsets of the data which are candidates for caching? For example, in social apps the last x hours of data drive virtually all the load.

  • What cache hit % do you need to achieve in order to benefit from the cache? (This is driven by your app's sensitivity to latency)

  • What is the ratio between reads/writes?

  • What are the consistency and reliability requirements?

  • What types of reads does your app do? Complex queries? Simple GETs? In which mix?

Caching layers can be incredibly effective when used correctly. But they aren't a silver bullet. Don't expect to just slap one over your existing store and magically get "faster" or "more scalable"...
