In the past couple of episodes, we’d gone over what Apache Kafka is and along the way we mentioned some of the pains of managing and running Kafka clusters on your own. In this episode, we discuss some of the ways you can offload those responsibilities and focus on writing streaming applications. Along the way, Joe does a mighty fine fill-in for proper noun pronunciation and Allen does a southern auctioneer-style speed talk.

Kafka Compatible and Kafka Functional Alternatives

Why? Because running any type of infrastructure requires time, knowledge, and blood, sweat and tears

Confluent

https://www.confluent.io/confluent-cloud/pricing/
We’ve personally had good experiences with their Kafka as a service

WarpStream

https://www.warpstream.com/
“WarpStream is an Apache Kafka® compatible data streaming platform built directly on top of object storage: no inter-AZ bandwidth costs, no disks to manage, and infinitely scalable, all within your VPC”
ZERO disks to manage
10x cheaper than running Kafka
Agents stream data directly to and from object storage with no buffering on local disks and no data tiering.
Create new serverless “Virtual Clusters” in our control plane instantly
Support different environments, teams, or projects without managing any dedicated infrastructure
Things you won’t have to do with WarpStream
- Upscale a cluster that is about to run out of space
- Figure out how to restore quorum in a Zookeeper cluster or Raft consensus group
- Rebalance partitions in a cluster
“WarpStream is protocol compatible with Apache Kafka®, so you can keep using all your favorite tools and software. No need to rewrite your application or use a proprietary SDK. Just change the URL in your favorite Kafka client library and start streaming!”
Never again have to choose between reliability and your budget. WarpStream costs the same regardless of whether you run your workloads in a single availability zone, or distributed across multiple
WarpStream’s unique cloud native architecture was designed from the ground up around the cheapest and most durable storage available in the cloud: commodity object storage
WarpStream agents use object storage as the storage layer and the network layer, side-stepping interzone bandwidth costs entirely
Can be run in BYOC (bring your own cloud) or in Serverless
- BYOC – you provide all the compute and storage – the only thing that WarpStream provides is the control plane
  - Data never leaves your environment
- Serverless – fully managed by WarpStream in AWS – will automatically scale for you even down to nothing!
Can run in AWS, GCP and Azure
Agents are also S3 compatible so can run with S3 compatible storage such as Minio and others

RedPanda

Redpanda is a slimmed down native Kafka protocol compliant drop-in replacement for Kafka
There’s even a Redpanda Connect!
It’s main differentiator is performance, it’s cheaper and faster

Apache Pulsar

Similar to Kafka, but changes the abstraction on storage to allow more flexibility on IO
Has a Kafka compliant wrapper for interchangability
Simple data offload functionality to S3 or GCS
Multi tenancy
Geo replication

Tip of the Week

Chord AI is an Android/iOS app that uses AI to figure out the chords for a song. This is really useful if you just want to get the quick jist of a song to play along with. The base version is free, and has a few different integration options (YouTube, Spotify, Apple Music Local Files for me) and it uses your phones microphone and a little AI magic to figure it out. It even shows you how to play the chords on guitar or piano. The free version gets you basic chords, but you can pay $8.99 a month to get more advanced/frequent chords.

Pandas is nearly as good, if not better than SQL for exploring data

Another tip for displaying in Jupyter notebooks – to HTML() your dataframes to show the full column data

Take photos or video and convert them into 3d models
