3. Overview
• Amazon DynamoDB
• Getting Started
• Best Practice

4. Amazon DynamoDB
• Fully Managed NoSQL Database Service
• Unlimited traffic & storage :D.
• Scaling without downtime.

5. Getting Started with DynamoDB
• Define Primary Keys
– Hash
– Hash and Range
• Provisioned throughput:
– Read Operation :
Read Operation Per Second * Read Operation Data/ 4KB
– Write Operation:
Write Operation Per Second * size of item/1KB
• Note: You will be charged priced per hour of
provisioned throughput

6. Example

7. Getting Started with DynamoDB
• Optional Element
– Secondary Index
• Local Secondary Index
• Global Secondary Index
• Transaction
Item Level Transaction only. Puts, updates,
deletes, are ACID.

8. Local Secondary Index
• Hash key is the same with primary index
• Consume Read & Write from table

9. Global Secondary Index
• Hash Key can be different from hash Index
• Every read & write has its own provisioned
throughput setting
• Notes: Global Secondary Index is like create a
new table that has the same content, but
different index. Meanwhile, local secondary
index is the same table with the different
range key.

10. Minus
• Cannot Modify Table Index
• You cannot query for not indexed attribute.

11. Best Practice
• Big Data Upload to S3
– DynamoDB only for Pointer
• Design Uniform Workload
– Avoid limited hash key values,
– Use distinct hash key values.
