Scaling Without Limits: KFIN's Journey to Distributed SQL
summary
KFin migrates core processing to YugabyteDB and reports concrete wins: an ingestion layer that moves 50 million transactions per day via microbatching, a cluster that grew from 3-node to a 12-node cluster plus a 6‑node DR with xCluster replication, steady 10k ops/sec in production and benchmarks to 40k ops/sec (CPU up to 80%), OLAP achieved by schema and query redesign, p99 targets near 1s, zero additional infra cost for the year.
