#DynamoDB is the most magical AWS Service, so @alexbdebrie & I decided to put on a magic show w/ @momentohq! #ddb_magic
Our favorite DynamoDB magic numbers in🧵will help you become an expert table magician by learning key internals!
What's your favorite magic number?
6.94
On-Demand IOPS cost 6.94x provisioned iops, but on demand is often cheaper! Why?
1\ 6.94 assumes 100% utilization. Nobody gets 100% utilization IRL!
2\ Autoscaling requires a predictable load cycle & fine tuning
3\ You can mix & match.

DynamoDB GSI (Global Secondary Index) are magical if used properly.
A primer 🧵 on how they work to help you make the most of them…

0\ You are listening to a DynamoDB Stream on table A. Whenever you see an item with a specific attribute, you insert it into table B with the attribute as the primary key.
👆 this is a GSI in a nutshell! Internalize this - and GSIs will make 💯 more sense..

A customer was considering leaving #dynamodb due to costs.
@pj_naylor and I helped them save half a million dollars per year with one simple, magical, optimization.
Want to save DynamoDB costs like a pro? Let’s start with some background…
1\ DynamoDB writes are 20x more expensive than reads. If you have 5 GSIs, you may be doing 6 writes every time you write a single item into a DynamoDB table.
The 20x is not a typo. More on that soon.

#DynamoDB strongly consistent reads are magical, but not for the reason most of us think.
SC reads have higher latencies, lower availability, and cost more - but worth it if you use them for the right reasons.
🧵👇explains what they are & how to unlock their real power!
0\ Primer: Doug Terry does a phenomenal job explaining the various consistency models through an illustrative exercise: microsoft.com/en-us/research…
