[Tiered Caching][Milestone 1] Integrate disk cache #11897
Description
Is your feature request related to a problem? Please describe
This is part of overall Tiered caching miletone 1 - #10870
As part of this, we want to integrate a disk cache which will extend the existing in-memory cache and be provided under the overall tiered cache option. Below are the requirements for that:
- We need an embedded cache library in JAVA.
- Cache should have disk tier support.
- Robust, performant, full proven and widely adopted.
- Opensource (preferably Apache v2 license).
There are the possibly three options we have fulfilling above requires:
- JCS
- Ehcache
- MapDb - (Don't see much active development from the past year, so will skip)
We are going with Ehcache in phase-1 as it is more widely adopted, has a better community support and we already have some experience with it as we did POCs with it.
Describe the solution you'd like
As described above, we are integrating ehcache as a disk cache option.
