主题:Re: How many TB to be store in riak
Hi Jason,
Random reads in LevelDB won't be an issue. It's also worth noting that the
bitcask backend will do at most one disk seek per read but this comes in
exchange for keeping you key directory in RAM. I still think Level is the way
to go for you.
The 50MB file size will probably be an issue. We don't usually recommend
anything over 20MB at this point, and even that might be problematic.

On second thought, let's assume you have 100TBs worth of photos. (I'm sure
there are a few individual photos somewhere on the internet that come it at
100TBs but I'm betting you don't have them).
Riak should work well for this.
* I'm assuming you'll have a lot of keys, so the LevelDB backend is probably
going to be best for local storage. We are also shipping LevelDB with Snappy
compression enabled as of 1.1, so this will help with the disk storage
requirements.
* Try to keep your file size under 20MB if possible.
* Keep in mind that 100TB with a default of 3 for a replication will yield
300TB of raw data.
Feel free to fire more questions as they come to mind.
Hope that helps.
Mark

Hi Jason,
I just want to make sure I understand your question correctly:
Do you have 100TBs of photos you are thinking of storing in Riak? Or one photo
that's 100TB?
