India vs Pak 250K RPS Latency Spike & Buffer Storm

The production step-by-step fix for this incident, derived from the validated mitigations.

1. 1Increase the Redis connection-pool size and add read replicasThe connection pool was saturated under the surge; expanding the pool and offloading reads to replicas relieves the exhaustion.
2. 2Add Kinesis shards to clear the ingestion lagShard lag grew because throughput exceeded provisioned shard capacity; resharding restores headroom and drains the backlog.
3. 3Cache DRM license tokens to remove the validation stallDRM validation blocked on per-request license checks; caching valid tokens removes the stall from the playback hot path.
