01_The_Problem
Slow queries and growing storage costs under heavy write loads.
02_Architecture_Solution
Reshaped collections to reduce document size and lock contention. Added targeted compound and partial indexes; rewrote hot aggregation pipelines to use $lookup sparingly and lean on precomputed fields. Cut query latency and reduced disk footprint significantly.
