@ArtOfCode at what scale? (I love it cause I started with it and used it for years so I know I'm heavily biased - and anything looks better than the Oracle stuff I have to use now)
I actually didn't mind SQL Server - and the reasons I hated MySQL I've found were more due to the way it was (ab)used than any failing of the software so pg or mysql at large scale might be another one of those
luckily most of my stuff now-a-days is Spark or Mongo with some SQLite databases used to feed them (usually can avoid the Oracle stuff but then there are those weeks....)
I will say: MySQL & SQLite seem to have the most SQL Injection answers on SO by far (presumably because they're the DB used most for beginner programmers)
"Each SPARC M5 processor provides six cores, with each core able to switch between up to eight threads (48 threads per processor) using a modified LRU (Least Recently Used) algorithm for thread choice." - So, 1532 threads ...
@Shog9 We tried using H2 for a project recently (I pushed for SQLite but was overruled by a lead who wanted to stick with something made in Java) only to completely reverse that decision and move everything over once he tried to use it (tried being the operative word - apparently the latest version doesn't allow for command line database creation)
Oracle licensing can cost over 2M / year: dba-oracle.com/t_licensing_pricing.htm (old prices); I guess if people pay that it's because it saves them money.
