• Durability
• Availability 
• Performance
• Consistency model - strongly consistent - 
• No ACID - Atomicity, I - Isolation

Operations

• create table
• put (table, key, value
• get (table, key) -> value
• delete (table, key)
• List ( keys in table in ...)

Sequence

timestamp + unique per row  + unique id

in ns                 4 bytes                  4 bytes   = 16 bytes 

8 bytes                                           2^32
