This is perhaps the most important concept in DynamoDB.
Sort Key Design.
If you're using DynamoDB like a regular NoSQL database, you are using it wrong.
Your sort key is the key (pun intended) to powerful and efficient queries.
Whether you have a billion items or 10 items your sort key design will dictate how efficient your queries will be.
Sort keys give you the opportunity to model your data in a hierarchical manner, enabling powerful filtering.
Say your database stores properties data for example.
You can have your sort key adopt this structure:
#US#NEWYORK#MANHATTAN
With this design, you can get all properties in the U.S with a single query.
You could also get all properties in New York, or go deeper and get all properties in Manhattan.
The reason this design makes for super efficient and powerful queries is because even if you have a trillion items in your table, the query latency will be the same as if you had 10 items:
Under 10ms fast.
That is mind-boggling.
How is that done exactly?
