The density of the DIMMs is where the price difference jumps. Right now 32GB sticks push the price way up. Common current chassis have 24 slots letting you hit 384GB total with no …

I think the focus on in-memory only is what makes Redis great and I hope they never change. It lives on that requirement and is incredibly stable and fast. I don't want another hal…

I just poked around with some of our servers to verify. In Softlayer's Dallas facility (selected when ordering a server) 10 Gbps is an option. The maximum amount of bandwidth avail…

That does seem odd. I'd file a ticket and see what they have to say about it. In certain datacenters (think might be dallas05?) you can even get a 10Gbps uplink brought to a box so…

Softlayer offers this as well. You can spec out a box however you want up to pretty exotic configurations, get billed monthly, and can SSH into them in 3-4 hours. It is expensive, …

If I need to go cross-shard then I am doing it in code. If you knew both shards were on the same box you could do cross-shard joins if you used schemas like this but you would need…

Good point, sounds like I intend to keep it that way for this particular database in my comment. It's setup for multi box (each schema is mapped to a hostname in code) but I simply…

I'm a big fan of Redis precisely because it has a short list of promises and executes them well. So many of these other new data stores promise "infinite scale" and leave out the "…

I have a 1.5 TB Postgres database, sharded by schema, that runs wonderfully on a single box (12 core, 36GB RAM, raid 10 of 15k SAS drives). Why couldn't you shard with Postgres?

The tough thing about comparing these two is that it is hard to find a benchmark (I don't know of one) that works similarly with them both. Sysbench is somewhat of a standard for t…

Compared to MyISAM? Sure for certain aggregate functions, but it's too easy to point out reasons for avoiding MyISAM: fragmentation, no transactions, table locks on writes, complet…

Postgres has bitmap index support baked in as well and it works really well. I'd be awfully interested in knowing where MySQL beats it by 50x at anything.

I am not a big fan of Hadoop. It is a headache to configure and optimized for installs with node counts only a few companies could make use of. I really wish there were more option…

Agreed, hard drives fail constantly. I've had as many as 3 dead at a time while waiting for hot spares to rebuild in arrays as small as 24 drives. Dual drive failures have happened…

There are some nice middle options out there. I'll use Softlayer as an example as I have provisioned a lot of machinery over there. I can order machines online and SSH in 3-4 hours…

We do have transactional support via Amazon SES now: http://blog.mailchimp.com/mailchimp-launches-transactional-e... It rolled out this very week.

If shopping for an SSD at least consider the OCZ Vertex. I've been running one in my Santa Rosa MBP for 7 months with no issues and excellent performance. See ( http://blog.gtuhl.c…

While I think some of these new projects are great for certain tasks, this sentiment resonates with me often when talking with nosql evangelists.

Thought I was add that the PostgreSQL documentation is really, really good for learning. It is a bit dense but overall very well written, includes nontrivial examples, and you can …
