Data modelling and partitioning in Azure Cosmos DB (Azure Cosmos
DB でのデータ モデリングとパーティション分割)
Session's objectives
What is Azure Cosmos DB? Non-relational and horizontally scalable
What is Azure Cosmos DB? horizontally scalable
What is Azure Cosmos DB? non-relational
What is Azure Cosmos DB? non-relational and horizontally scalable
So is Azure Cosmos DB suitable for relational workloads?
Let's look at a concrete example
Identifying the operations we have to serve
Now let's implement this model on Azure Cosmos DB!
Starting with the Customer entity
Starting with the Customer entity
To embed or to reference?
To embed or to reference? - - - - -

Our first entity: Customer
Customer customers PK: ?
What is partitioning?
What is partitioning? logical partitions

* FROM c WHERE c.favoriteColor = 'orange' ?
Choosing a partition key for customers customers PK: ?

Next: product categories
Product categories
Product categories productCategories PK: ?
Product categories productCategories PK: ? SELECT * FROM c
Product categories productCategories PK: type
Next: product tags
Product tags

Products
Products products PK: ?
Products products PK: ? CategoryA CategoryC CategoryB SELECT * FROM
c WHERE c.categoryId = 'CategoryA'
Products products PK: categoryId category name? tag names?
Products: how to return category and tag names? products SELECT
* FROM c WHERE c.categoryId = 'CategoryA' productCategories SELECT c.name FROM c WHERE c.id = 'CategoryA' productTags SELECT * FROM c WHERE c.id IN ('<tagId1>', '<tagId2>', '<tagId3>')
Introducing denormalization
Products: denormalizing category and tag names products PK: categoryId
Products: keeping everything in sync productCategories productTags products
Cosmos DB's change feed
Products: keeping everything in sync productCategories productTags products
Next: sales orders
Sales orders
Sales orders
Sales orders salesOrders PK: ?
Sales orders salesOrders PK: ?
Sales orders salesOrders PK: ? CustomerA CustomerC CustomerB SELECT *
FROM c WHERE c.customerId = 'CustomerA'
Sales orders salesOrders PK: customerId
Sales orders salesOrders PK: customerId customers PK: id
Mixing entities in the same container?
Sales orders salesOrders PK: customerId customers PK: id
Sales orders: mixing with customers customers PK: id
Sales orders: mixing with customers customers PK: customerId
Sales orders: mixing with customers customers PK: customerId
Sales orders: mixing with customers CustomerA CustomerC CustomerB customer sales
orders customers PK: customerId
Sales orders customers PK: customerId SELECT * FROM c WHERE
c.customerId = 'CustomerA' AND c.type = 'salesOrder'
Sales orders customers PK: customerId
Denormalizing the count of sales orders per customer
Denormalizing the count of sales orders per customer
Denormalizing the count of sales orders per customer CustomerA CustomerC
CustomerB customer sales orders customers PK: customerId
Denormalizing the count of sales orders per customer CustomerA CustomerC
CustomerB update the customer add a sales order customers PK: customerId
Denormalizing the count of sales orders per customer CustomerA CustomerC
CustomerB update the customer add a sales order
Sales orders customers PK: customerId SELECT * FROM c WHERE
c.type = 'customer' ORDER BY c.salesOrderCount DESC
Our final design customers PK: customerId productCategories PK: type productTags
PK: type products PK: categoryId
Our final design, optimized! customers PK: customerId productMeta PK: type
products PK: categoryId
