I was asked to do a magazine article on NoSQL, where by “NoSQL” is meant “whatever they talk about at NoSQL conferences.” By now the number of publications planning to run the article is up to 2, the deadline is next week and, crucially, it has been agreed that I may talk about HVSP in general, NoSQL and SQL alike.
It also is understood that, realistically, I can’t be expected to know and mention the very latest news for all the many products in the categories. Even so, I think this would be fine time to check just where NoSQL and HVSP adoption stand. Here is most of what I know, or links to same; it would be great if you guys would contribute additional data in the comment thread.
In the NoSQL area:
- Back in April, the VoltDB guys told me they thought Cassandra and HBase were the two NoSQL systems with the most momentum.
- I know distressingly little about HBase adoption, but a source who may or may not wish to remain anonymous was kind enough to alert me that Twitter and StumbleUpon each have ~30 node deployments, for analytics and analytics/HVSP respectively.
- I wrote in detail on Cassandra adoption last month. News since then includes:
- Facebook is rumored to have dropped Cassandra completely.
- Twitter clarified that it may not be quite as lovestruck by Cassandra as before, but they’re still very close friends.
- It’s not obvious that the Cassandra Summit unveiled a lot of new adoption stories.
- Northscale’s Membase is still in its early days. Zynga is bought in, however, as is something called NHN Korea. (Edit: I subsequently saw NHN Korea on a prominent SEO expert’s list of the top half dozen or so search engines in the world. Who knew?)
- Basho has listed a few Riak customers. If memory serves (I haven’t spoken with Basho for a while, and some of my notes are misplaced due to some computer sloppiness), Basho has a few dozen customers in total.
- Mozilla has a 4 machine, 64 core Riak cluster in production.
- Hypertable has a few users/project sponsors, Baidu being the biggest name among them.
- I don’t really know how the MongoDB/10gen guys are doing. I think this is at least as much my fault as theirs. Anyhow, they seem to have links to a couple of folks who have written about MongoDB usage.
- NimbusDB is still in stealth mode. I’d be surprised if they had users for a while yet, since in January they didn’t yet sound as if development was very far underway. (Actually, I forget whether NimbusDB is supposed to be SQL-based or not.)
Among the SQL or SQL-friendly guys:
- Clustrix says it has a few production users, some big-name, but is not disclosing them yet.
- dbShards has around 6 customers, including Facebook. (Facebook may outpace even Twitter and Zynga in using the most products mentioned in this post.)
- As of May, VoltDB had one paying customer, plus 150 beta customers who weren’t in production yet.
- Akiban says they’ll get me up to speed on Thursday.
- ScaleDB seems to be pedaling along in perennial beta. Whether ScaleDB has any actual beta users is less clear. On the plus side, checking that out uncovered a pretty funny April Fool blog post.
- Groovy Corporation seems to have disappeared, or morphed into something called uCirrus, or something like that.
