Benjamin Lerer commented on CASSANDRA-16806:
--------------------------------------------
{quote}Firing an exception with the message DELETE statements must restrict all
PRIMARY KEY columns with equality relations in order to use IF condition on non
static columns when it is not supported by the table seems a bit weird to
me.{quote}
Sorry, for the confusion. What is not supported on Virtual tables is
conditional updates/deletions. Static columns are. We just do not have any
virtual tables that use them so far.
[~cnlwsu] We are looking for a second reviewer. Would you have the time for it?

> {{TRUNCATE}} statements are currently not supported by Virtual Tables. For
> some Virtual Tables it makes sense to allow it.
> It can be done by adding a {{truncate}} method to the {{VirtualTable}}
> interface and calling that method from {{TruncateStatement}}. The default
> implementation of the method should be to fire an {{InvalidRequestException}}
> saying that truncate is not supported on that specific table.
