clj on windows
View winclj.md

Setting up clojure on windows for beginners.

I tried 3 ways:

  • Install a windows linux sub-system - this was too hard to setup
  • Setting all deps from ground-up (git, java, curl etc.) - this was too hard to setup
  • Using scoop - this is the simplest way, described below

Note: this has only been tested on Windows 10

some notes on using pg_repack
View pg_repack.md

so if table is 350g, free space should be = 700

given you current DB = 900gb, and your disk = 1.3gb, you should bump it up to at least 1.6tb

that will ensure 20% free space and space for an additional table

things to keep in mind before using repack:

1. response time during repack *will* increase – make sure you do it at night
