Flash Talks
summary
A rapid set of concrete takeaways and tools: a MongoDB oplog→Postgres pipeline that moves from 8h to ~1.3h with goroutine fan‑out and worker pools but hits ordering bugs (updates before inserts) — 6x speedup; a Postgres-based distributed lock using select for update + nowait + skip locked for queueing across processes; ClickHouse using SummingMergeTree to reconcile rolling commission records in one query; confinement as a pattern that avoids mutex-induced slowdowns; go:embed and go generate examples for bundling configs and producing JSON schemas.
