1.8 18:57:33 very nasty bug fixed! joins were copying tuples into their internal buffers,
BUT they were keeping pointers to the original parameters... i.e.,
somewhere on the input queue.
2004/10/08 yna Changed box packing interface to use smart pointers.
Updated any existing boxes that packs states.
2004/10/05 mbalazin - Checkpointing state of Join operators.
- Doing checkpoint/redo to reconcile state of joins when necessary.
- Added a void unpackQueue(const QueueState& packed_queue); method to QBox.
2004/09/30 mbalazin Reconciling join state with undo/redo.
2004/09/28 mbalazin To avoid modifying the Join operator code, I added a user-defined join operator that supports state reconciliation after failures.
I noticed that our Join operator doesn't manage its windows quite correctly but I don't want to touch that at the moment. The problem appears when the window is small and tuples arrive in large batches rather than roughly simultaneously.
I only added a "clear()" method to our current join operator. The method clears the operator state.
Minor improvements in ConsistencyMngr and SUnionQBox.
2004/09/24 yna Moved most of the Aurora code into the Borealis namespace. There are still a few things in util/ that aren't
used that need to be moved.....
2004/09/17 bb Updated with Long, Single and Double schema.
2004/04/14 mbalazin New dir structure
