NoSQL and Redis

Dave said "this preceded NoSQL I imagine", and he was referring to key/value stores in general I believe, which are indeed older than relational databases and are a layer on top of which relational databases are built.

When I initially heard it, I thought it referred to Redis specifically, and I thought "no way, Redis came out in the middle of the NoSQL boom".

I was wrong, by two days. :-D

Redis came out on 2009-05-10 and the term NoSQL in the current sense was coined on 2009-05-12.

Redis pronunciation

Most people pronounce it /reddis/, not /reedis/.

It is often used as a cache to avoid expensive database lookups, much like one would use e.g. memcache, and I've always interpreted the name to hint at "I don't need to make that heavy multiple-tables join, because I know I already 'read this' just a moment ago".

I've never looked up what the official story of the name is.

Key/value storage

Hi Clacke,

What I couldn't recall at the time was the name Berkely DB. I used this for a while when it was owned by a company called Sleepycat. Later it was bought by Oracle.

We were OpenLDAP users at the university I worked at, and this ran on top of Berkely DB files. I failed to remember all of this in the show itself of course :-)

OpenLDAP on BDB?

I didn't know OpenLDAP originally ran on BDB! These days it uses its own LMDB, which has also replaced BDB in many other places.

Turns out, OpenLDAP started using BDB in 2002 and LMDB wasn't ready until 2011. In the middle of the NoSQL boom! :-)
