- The @INSERT@ statement writes one or more columns for a given row in a table. Note that
since a row is identified by its @PRIMARY KEY@, the columns that compose it must be specified.
Also, since a row only exists when it contains one value for a column not part of the @PRIMARY
KEY@, one such value must be specified too.
+ The @INSERT@ statement writes one or more columns for a given row in a table. Note that
since a row is identified by its @PRIMARY KEY@, at least the columns composing it must be
specified.
  
 -Note that unlike in SQL, @INSERT@ does not check the prior existence of the row: the row
is created if none existed before, and updated otherwise. Furthermore, there is no mean to
know which of creation or update happened. In fact, the semantic of @INSERT@ and @UPDATE@
are identical.
 +Note that unlike in SQL, @INSERT@ does not check the prior existence of the row by default:
the row is created if none existed before, and updated otherwise. Furthermore, there is no
mean to know which of creation or update happened.
 +
 +It is however possible to use the @IF NOT EXISTS@ condition to only insert if the row does
not exist prior to the insertion. But please note that using @IF NOT EXISTS@ will incur a
non negligible performance cost (internally, Paxos will be used) so this should be used sparingly.
  
  All updates for an @INSERT@ are applied atomically and in isolation.
