Subject Re: [DISCUSS] FLIP-19: Improved BLOB storage architecture
Date Wed, 14 Jun 2017 10:29:55 GMT
One thing i was wondering for a long time now is why the distributed 
cache is not implemented
via the blob store.

The DC is essentially just a copy routine with local caching and 
automatic cleanup, so basically what
the blob store is supposed to do (i guess).
