Local Development Techniques with Kubernetes

This talk is all live demos of tools developers can use in their inner-loop, at development time to be more productive with containers.

Start Easier

Docker Compose captures the build arguments and run arguments so we can focus on our coding.

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:

#Even though Armin beat me to the punch with an accepted answer I thought I'd show an abbreviated example of how I implemented a regex matcher in Flask just in case anyone wants a working example of how this could be done.

from flask import Flask
from werkzeug.routing import BaseConverter

app = Flask(__name__)

class RegexConverter(BaseConverter):
