------------------------------------------
Summary: Delete operation not deleting sometimes by Trigger
augment method
Key: CASSANDRA-10599
URL: https://issues.apache.org/jira/browse/CASSANDRA-10599
Project: Cassandra
Issue Type: Bug
Components: API, Core, Examples, Tools
Environment: CentOS 6.6 Cassandra 2.2.2
Reporter: Ashraful Islam
I was trying to delete a row from one table when another table's row with the
same primary key has been deleted
{code:title=DeleteToDelete.java|borderStyle=solid}
@Override
public Collection<Mutation> augment(ByteBuffer key, ColumnFamily
update) {
String keySpace = properties.getProperty("keyspace");
String columnFamily = properties.getProperty("table");
if (!update.deletionInfo().isLive()) {
CFMetaData cfMetaData =
Schema.instance.getCFMetaData(keySpace, columnFamily);
for (ColumnDefinition columnDefinition :
cfMetaData.allColumns()) {
System.out.println(CellNames.simpleSparse(columnDefinition.name));
Mutation mutation = new Mutation(keySpace, key);
mutation.delete(columnFamily,
CellNames.simpleSparse(columnDefinition.name), System.currentTimeMillis());
}
}
}
{code}
*This code is not deleting row with the same key that have been inserted with
insert into values command.*
*but if i insert the value by replacing*
{code}
mutation.delete(columnFamily, CellNames.simpleSparse(columnDefinition.name),
System.currentTimeMillis());
{code}
*by*
{code}
mutation.add(columnFamily, CellNames.simpleSparse(columnDefinition.name),
ByteBufferUtil.bytes(35), System.currentTimeMillis());
{code}
*in the above code, Then the value is deleted with the trigger*
