The following attributes are automatically provided i.e if the attribute is present in the table, CQL will automatically fill in the value:

1. generation_ Set to 0 on INSERT and incremented by 1 on each update
2. inserted_ Set to the current time at the time of the INSERT transaction
3. inserted_by_ Set to the user ID corresponding to the access token supplied to the transaction
4. updated_ Set to the current time at the time of the UPDATE transaction. Note that updated_ is also set by an INSERT
5. updated_by_ Set to the user ID corresponding to the access token supplied to the transaction. Note that updated_by_ is also set by an INSERT

All the special attributes can be overridden by supplying the attribute-value pair explicitly.
