Subject [DISCUSS] Should L2 cache be strictly L2 by default
Date Thu, 17 Aug 2017 18:23:47 GMT
Currently BUCKET_CACHE_COMBINED_KEY is set to "true" by default  [1] which
makes L2 cache not strictly L2 cache. From the usability perspective, it is
better to set BUCKET_CACHE_COMBINED_KEY  to "false" so that L2 cache would
behave strictly L2 and also use the L1 cache to store data blocks improving
memory use. Thoughts?

Thanks,
Biju
