// # Mocha Guide to Testing | |
// Objective is to explain describe(), it(), and before()/etc hooks | |
// 1. `describe()` is merely for grouping, which you can nest as deep | |
// 2. `it()` is a test case | |
// 3. `before()`, `beforeEach()`, `after()`, `afterEach()` are hooks to run | |
// before/after first/each it() or describe(). | |
// | |
// Which means, `before()` is run before first it()/describe() |

sh (or the Shell Command Language) is a programming language described by the POSIX standard. It has many implementations (ksh88
, dash
, ...). bash
can also be considered an implementation of sh (see below).
Because sh is a specification, not an implementation, /bin/sh is
a symlink (or a hard link) to an actual implementation on most POSIX systems.
- Create
UNLOGGED
table. This reduces the amount of data written to persistent storage by up to 2x. - Set
WITH (autovacuum_enabled=false)
on the table. This saves CPU time and IO bandwidth on useless vacuuming of the table (since we neverDELETE
orUPDATE
the table). - Insert rows with
COPY FROM STDIN
. This is the fastest possible approach to insert rows into table. - Minimize the number of indexes in the table, since they slow down inserts. Usually an index
on
time timestamp with time zone
is enough. - Add
synchronous_commit = off
topostgresql.conf
. - Use table inheritance for fast removal of old data:
