The following attributes are automatically provided i.e if the
attribute is present in the table, CQL will automatically fill in the
value:
- generation_ Set to 0 on INSERT and incremented by 1 on each
update
- inserted_ Set to the current time at the time of the INSERT
transaction
- inserted_by_ Set to the user ID corresponding to the access
token supplied to the transaction
- updated_ Set to the current time at the time of the UPDATE
transaction. Note that updated_ is also set by an INSERT
- 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
- transaction_id_ Set to the transaction ID
All the special attributes can be overridden by supplying the
attribute-value pair explicitly.
