      The five cache usage configuration options eviction_checkpoint_target, eviction_dirty_target, eviction_dirty_trigger}, {{eviction_target and eviction_trigger are currently specified as percentages of the cache size.

      When users configure very large caches, it would be useful if the settings could take more precise values than percentages. For example 1% of 1TB is still a lot of dirty content to allow in cache. A method for achieving this would be to support decimal values in the configuration string.
