ryan	160e63558f	fix(clickhouse): harden R/W path P0–P3 (cleanup, durability, rollups) ... Honest TTL cleanup semantics; enqueue-safe dedup with flush retry and writer metrics; model insert hooks; latest-per-node and hourly metric/openresty rollups; small-host pool/async defaults, traffic hourly TTL, and UV labeling.	2026-07-10 10:34:04 +08:00
ryan	9b3555c569	fix(clickhouse): cut idle CPU from tiny parts and oversized merge pools ... Observability writers flushed every few seconds with MinBatchSize unset, creating constant small parts and merge load. Enable MinBatchSize with MaxFlushWait, batch access logs more aggressively, and shrink ClickHouse background pools for 3c hosts.	2026-07-10 10:08:32 +08:00
ryan	ae618905a3	perf(clickhouse): P0 write path — remove heartbeat DELETE, batchwriter MinBatchSize, tune chwriter	2026-07-02 15:23:17 +08:00
ryan	8c872f9b32	refactor(bootstrap): 引入解耦的全局生命周期管理器以隔离业务停机钩子 ... - 新建 internal/lifecycle 包，提供全局线程安全的 Shutdown 钩子注册与调度能力。 - 在 chwriter 与 risk_control 初始化阶段通过 OnShutdown 将其 Stop 函数注册到管理器中。 - bootstrap.Stop() 函数仅委托调用 lifecycle.Stop()，不再硬编码引入业务包，防止后续框架同步产生合并冲突。	2026-06-20 09:58:59 +08:00
ryan	9491b2a744	feat(clickhouse): wire batchwriter into business ingestion paths ... Migrate risk_control audit logs to internal/db/batchwriter and add openflare/chwriter with per-table async flush for observability timeseries and node access logs. Replace single-row ClickHouse inserts and pre-insert SELECT count() dedup with repository BatchInsert* APIs, in-process TTL dedup for metric/report snapshots, and bootstrap initialization on API startup.	2026-06-19 17:20:39 +08:00
