Snowplow Redis Integration

Redis turns your enriched Snowplow events into a real-time, queryable store with sub-millisecond reads — ideal for personalization, in-session decisioning, and live dashboards. SnowcatCloud's integration writes one Redis HASH per event under an `events:` prefix, with every top-level Snowplow field automatically exploded into its own hash field. Nested fields like contexts and unstruct_event keep their JSON-string value inside the hash, and event timestamps are added as epoch-millisecond fields so they can be sorted and range-queried with RediSearch. Combined with Redis Cloud's allkeys-lru eviction policy, you get a self-managing hot window of behavioral data — no schema design, no manual cleanup, no per-event TTL bookkeeping required.
