------------------------------------------
Summary: Add triggers support to LWT operations
Key: CASSANDRA-6882
URL: https://issues.apache.org/jira/browse/CASSANDRA-6882
Project: Cassandra
Issue Type: New Feature
Components: Core
Reporter: Sam Tunnicliffe
Assignee: Sam Tunnicliffe
Priority: Minor
Fix For: 2.0.7
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.
