    How-to: Migrating repos on Github to a monorepo

To avoid peppering too many opinions in this “how to” guide, I’ve written a separate “opinion-piece” article on monorepos — you can read it here: https://medium.com/streamdal/mostly-terrible-the-monorepo-5db704f76bdb
Sometime in early Dec 2023, our team decided to migrate ~10 public repositories for an OSS project to a monorepo.
This article provides a “rough” outline for the meatiest parts of the migration.
Good luck! 🤞

                Notes about Pulsar
              
          
    I compiled these while learning about running Apache Pulsar. The notes are written from the perspective of a Go developer
that interfaces primarily with Kafka, RabbitMQ and NATS. Something may not be entirely correct. Sorry!

Concept of “bundles”
Each broker is in charge of certain bundles
A bundle represents multiple topics
Pulsar has a tunable automatic load shedder
Possible to configure to auto shed bundles to less loaded brokers
Bundles are automatically split when under heavy load
Bundle is split into more bundles

# Download the better mc server pack zip file from curseforge. Move that to /root/minecraft/ggf-fabric-bmc/pack.
# Reference the zip file in GENERIC_PACK.
# docker-compose up -d and watch the logs. There will be lots of errors due to better mc using ~200 mods but it should start
# nevertheless.

                cassandra-stress notes
              
          
    I wasn't able to find any concrete examples of folks running cassandra-stress against TLS + auth enabled cassandra clusters;
this gist hopefully fulfills that.
Setup


3 node C* setup w/ lucene running on instaclustr
TLS Enabled
Auth Enabled

Run
