|
||
|
|
- Structured data
|
||
|
|
- Strict schema
|
||
|
|
- Relational data
|
||
|
|
- Need for complex joins
|
||
|
|
- Transactions
|
||
|
|
- Clear patterns for scaling
|
||
|
|
- More established: developers, community, code, tools, etc
|
||
|
|
- Lookups by index are very fast

|
||
|
|
|
||
|
|
|
||
|
|
- Semi-structured data
|
||
|
|
- Dynamic or flexible schema
|
||
|
|
- Non relational data
|
||
|
|
- No need for complex joins
|
||
|
|
- Store many TB (or PB) of data
|
||
|
|
- Very data intensive workload
|
||
|
|
- Very high throughput for IOPS
|
||
|
|
|
||
|
|
## Sample data well-suited for NoSQL:
|
||
|
|
|
||
|
|
|
||
|
|
- Rapid ingest of clickstream and log data
|
||
|
|
- Leaderboard or scoring data
|
||
|
|
- Temporary data, such as a shopping cart
|
||
|
|
- Frequently accessed ('hot') tables
|
||
|
|
- Metadata/lookup tables
|
