We had two distros of Oracle DB, seven forks of MySQL from different vendors,
five DVDs with MS SQL Server, a saltshaker half-full flash drive with PostgreSQL debs,
source code for a whole galaxy of FOSS databases... Including Redis, Memcached, MongoDB, Elasticsearch, and Neo4j.
Not that we needed all that for the workshop, but once you get locked into a serious data warehousing,
the tendency is to push it as far as you can. The only thing that really worried me was the SQLite.
There is nothing in the world more helpless and irresponsible and depraved than in-process embedded serverless databases,
and I knew we'd get into that rotten stuff pretty soon.
