Ashraful Islam commented on CASSANDRA-10599:
--------------------------------------------
sorry for disturb again i am new in Cassandra
I have used org.apache.cassandra.utils.FBUtilities.timestampMicros() instead of
System.currentTimeMillis() but it's setting value_1 and value_2 value with the
same key to zero except the primary key id, it remain unchanged and not deleting
> Delete operation not deleting sometimes by Trigger augment method

> 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()) {
> 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*
