1. Apach Avro

2. Overview 1
Data serialization system or /and Data Exchange
Resolve Hadoop Writables : lack of portability
Sharing data
Language independent-schema (JSON)
No need for code generation

3. Overview 2
Supports schema evolution
Supports compression and splitting
Rich data types and schema

4. Avro Data types and Schemas 1
null
boolean
int
long
float
double

5. Avro Data types and Schemas 2
array
map
record
enum
fixed
union

6. Avro Data types and Schemas 3
Generic Java mapping
Specific Java mapping
Reflect Java mapping

7. In-memory Serialization and Deserialization

8. Specific API (avro-tool)

9. Datafiles
Schema
Avro object
Marker sync
In binary format

10. Datafiles

11. Portability

12. Portability

13. Schema resolution (Projection)

14. Sort Order
Every avro object has ordering rule except records
Comparing works directly on the byte streams
