event-sourcing是基于事件回溯的高性能架构，主要针对单个领域业务高度复杂且需要高性能的业务场景，可以说它能够作为高并发系统的通用解决方案。例如：秒杀、抢红包、12306卖票等。基于事件溯源，实现cqrs最复杂的模型， 通过事件是追加的特性，然后结合事件批量提交的手段，避免在高并发更新时多个线程update带来的严重锁冲突问题，从而来实现高性能。 支持聚合回溯，包括扩容、缩容聚合冲突事件回溯、聚合根在内存、聚合根快照、聚合事件组提交，可集成dubbo、spring cloud。

Durable disk-backed FIFO byte queue for Go: fsync-on-append with group commit, at-least-once delivery via explicit commit, byte-bounded backlog, and checksummed frames whose corruption is always reported, never silent

Embedded append-only event log in Rust. One writer thread groups many callers' appends into a single fsync. Per-stream revisions, expected-revision checks, idempotency keys, and a seal step that leaves the files on disk as history.
