Event and market id mapping

Answer: events have numeric id; markets use id = eventId:key (e.g. 1640278226:s;0;m). Cache your own fixture ↔ id map. After reconnect, rebuild from snapshot — do not assume ids vanished mid-session without a remove. Schema: docs.

Why it matters#

Algo-betting threads often call line id mapping the real bottleneck — not JSON parse time. Keep a local dictionary and update on upsert/remove only.
