The ETL pipeline processes on a 16‑node Spark cluster (AWS EMR). Graph construction time scales linearly with session length; the longest 1 % of sessions (≥ 2 000 events) are truncated to a depth‑limit of 50 peripheral actions to keep memory usage bounded.
Targeted Star Sessions could cater to specific micro‑audiences (e.g., adaptive fashion for differently‑abled models, or culturally specific aesthetics), fostering inclusivity while tapping underserved markets. lisamaisiess001 star session models link
