---------------------------------------------
Summary: Trigger Data Unmarshalling not working for Compose Data
Structures
Key: CASSANDRA-13602
URL: https://issues.apache.org/jira/browse/CASSANDRA-13602
Project: Cassandra
Issue Type: Bug
Reporter: Samuel Martinucci
Priority: Blocker
The following behavior was identified running Cassandra 3.10
I have the following trigger:
{code}
public class TestTrigger implements ITrigger
{
@Override
public Collection<Mutation> augment(final Partition update)
{
final UnfilteredRowIterator it = update.unfilteredIterator();
while (it.hasNext())
{
final Unfiltered un = it.next();
final Clustering clt = (Clustering) un.clustering();
final Row row = update.getRow(clt);
final Iterator<Cell> cls = row.cells().iterator();
while (cls.hasNext())
{
final Cell cell = cls.next();
System.out.println(cell.column().name.toString() + " "
+
cell.column().cellValueType().getClass() + " "
+
cell.column().cellValueType().compose(cell.value()));
}
}
return Collections.emptyList();
}
}
{code}
Configured for the following table:
{code}
CREATE TABLE IF NOT EXISTS audit_app_log
(
id text,
log_time timestamp,
mappings map<text,frozen<list<text>>>,
PRIMARY KEY((id),log_time)
)
AND CLUSTERING ORDER BY (log_time DESC);
{code}
When I insert data into this table, I have the following output:
mappings class org.apache.cassandra.db.marshal.ListType ["test"]
This output means that I am losing the key from the map, and seeing only the
internal data structure. Am I doing something wrong or this is really a bug?
