group-commit

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。

An LSM-tree storage engine in Rust with a crash-injection harness, write-ahead log, and group commit.

Crash-safe LSM-tree storage engine in C++20: WAL with group commit, SSTables, bloom filters, leveled compaction, snapshots. Tested with simulated power loss, injected disk errors, and fuzzing.

Bounded, crash-resistant write-ahead log for Go with explicit durability, atomic and streaming appends, recovery, and acknowledged consumption.

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
