  • Scripts to regenerate the results in Figure 5 ( Note: Before mounting any time ACA attacks to modified ALEX (forcing catastrohpic expansion instead of catastrohpic split) or vanilla ALEX, we need to comment/uncomment line 1316 to 1321 in alex.h, as described in paper)

3. Dependencies for Attacks

• Space ACA on data nodes: OR-Tools and KDE
• Space ACA on internal nodes: No dependencies
• Time ACA on ALEX: KDE

4. Datasets

Datasets (Longitudes, Longlat, Lognormal, YCSB) used in this paper could be found in ALEX repo.
