====== Quick Setup ======

For a quick setup with m and mtools on Debian/Ubuntu, download a script [[https://github.com/nitredd/provisioning/raw/refs/heads/master/mongo-playground-deb.sh|here]].

<code bash>
npm install -g m  # Aaron Heckmann's verion manager
# m 8.0.15
# m mongosh 2.5.9
# m tools 100.13.0
# PATH=$PATH::~/.local/m/tools/versions/100.13.0/bin:~/.local/m/shell/versions/2.5.9/bin:~/.local/m/versions/8.0.15/bin

python3 -m pip install mtools psutil pymongo  # Thomas Rucksteiss' mtools
# mlaunch --init --replicaset --nodes 1 --sharded 2 --port 28000
# mongosh --port 28000
</code>

====== Key-file login ======

<code bash>
mongo -u __system -p "$(tr -d '\011-\015\040' < path-to-keyfile)" --authenticationDatabase local
</code>

====== MongoSH JSON ======

To increase the levels of JSON nesting to display (from the default of 6), run the following:

<code javascript>
config.set("inspectDepth", Infinity)
</code>

====== Tuning for writes ======

<code>
db.adminCommand({
  setParameter: 1,
  wiredTigerEngineRuntimeConfig: "eviction_dirty_target=2,eviction_dirty_trigger=30,eviction_updates_target=2,eviction_updates_trigger=30,eviction=(threads_min=8,threads_max=8)"
})
</code>
