> Key: ASTERIXDB-3214
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-3214
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: STO - Storage
> Affects Versions: 0.9.9
> Reporter: Wail Y. Alkowaileet
> Assignee: Wail Y. Alkowaileet
> Priority: Major
> Fix For: 0.9.9
>
>
> Currently, the method markAsDeleted in LSMColumnBTreeRangeSearchCursor has
> the following implementation:
> {code:java}
> protected void markAsDeleted(PriorityQueueElement e) throws
> HyracksDataException {
> if (isMemoryComponent[e.getCursorIndex()]) {
> super.markAsDeleted(e);
> return;
> }
> IColumnTupleIterator columnTuple = (IColumnTupleIterator) e.getTuple();
> columnTuple.skip(1);
> } {code}
> The problem here is that if *columnTuple* is an anti-matter, we will skip
> non-key columns that do not belong to the anti-matter (as anti-matter tuples
> do not have anything besides the PKs). So, this should only skip non-key
> columns if the tuple is not an anti-matter one.
