> Currently, compactor threads make use of Guava package to cache metadata
> objects like database/table objects. We should consider using Caffeine
> package since it provides more control on the cache. It is also observed that
> cache created from Caffeine package is more performant than cache created
> from Guava package.
> Some benchmarks comparing Caffeine package vs Guava package -
