Django ORM Optimization Tips

Caveats:
* Only use optimizations that obfuscate the code if you need to.
* Not all of these tips are hard and fast rules.
* Use your judgement to determine what improvements are appropriate for your code.

Optimizing postgresql table for more than 100K inserts per second

• 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 never DELETE or UPDATE 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 to postgresql.conf.
• Use table inheritance for fast removal of old data:

# You have a model something like this

from django.contrib.postgres.fields import JSONField

class MyModel(models.Model):
    jsonfield = JSONField()  # {"name": "Gaurav", "age": "25", "address": {"country": "India", "city": "Jaipur"}}
    # few more fields...
    
# And in admin you want to create filter for jsonfield properties/keys
# for e.g. in above case we want to show filter for age and country

Docker Cli Tips and Tricks

My favorite command line options and best practices

• Bash/zsh completion
• use Tab to populate command line, narrows down options as you go, fills in container names, ID's, images, volumes. Huge time saver.
