>
> Currently, any triggers configured for a table are not executed during LWT
> operations. If we were to enable triggers support for conditional operations,
> we'd need to restrict the kinds of mutations that those triggers are
> permitted to generate. More specifically, we'd need to ensure that only
> mutations that apply to the same partition as the primary condition are
> allowed. If a configured trigger emits mutations for another partition, or a
> different table, then the whole operation should be aborted in the same way
> as we abort non-LWT updates when a trigger produces invalid mutations.
