Order Data Synchronization Architecture at YouZan: From MySQL to ES and HBase

YouZan’s order data synchronization moves changes from MySQL through Canal‑parsed binlogs into a message queue, then uses sequential SeqNo‑based optimistic locking and HBase’s column‑version timestamps to guarantee ordering for both single‑ and multi‑table updates, while a Logstash‑style configurable pipeline feeds ES for search and HBase for detail queries, eliminating ordered‑queue bottlenecks and ensuring high‑throughput consistency.
