Cage Match: MySQL vs NoSQL vs Postgres

A post by Brain Aker about the state of MySQL, Postgres and NoSQL databases.

I had a couple of comments and these evolved into a long rant.

MySQL became less interesting once it was acquired […]

I’ve never been very sure what metric is used to measure how interesting a product is. That in case there’s such a metric. As opposed to some suggestions I’m reading, I haven’t seen stories of people moving away from MySQL because Oracle acquired it. Except Fedora and OpenSUSE replacing MySQL with MariaDB and this due to very specific issues (no security infos, no access to regression tests).

the number of Postgres deployments is greater then what all of the NoSQL market combined adds up to

Comparing 15 years of PosgreSQL with 3 years of NoSQL isn’t going to give meaningful results (for a similar unbalanced comparisons try Oracle vs PostgreSQL). I’m not aware of any database that captured a significant market share in the first 3 years of its existance. Except MySQL. Not Postgres.

Would a document model really matter if schemas could be altered online?

Yes, it would definitely remain relevant. Schema flexibility is not only about updating it, but also about the types allowed. PostgreSQL has indeed added support for arrays and JSON. I see this as a confirmation of what’s happening in the NoSQL space and also about the future of storage engines.

no new language has emerged from the NoSQL market that has any size-able adoption

MongoDB’s query language and the aggregation framework are used by a lot of people. It’s probably not the ideal query language and it comes in two different flavors, but it’s there and it’ll most probably evolve. Biasedly, I could also point to RethinkDB’s data manipulation language for an example of something that is probably on par with SQL and without the hidden unknown corner cases of SQL. Indeed none of these can come close the the adoption acquired by SQL in its 30 years of existance.

Bottom line is that I expect bridges to be built between relational databases and NoSQL databases and each side adopting those features that are useful to their users. I also expect that slowly this relational databases are crap vs NoSQL databases are crap debate will go away, people realizing that the data space is not a zero sum game. Vendors will be the last to give up this fight, but customers have a lot of power in making this happen.
