- New internal/repository/logstore abstraction: exported domain interfaces
(AccessLogStore/ObservabilityStore/UserAccessLogStore/StatusStore),
config-driven provider (Active/Build/Migrating/SetConfigReader), GORM
implementation for PostgreSQL/SQLite (incl. hourly rollups computed in
real time, migration listers, PG partition maintenance), and a ClickHouse
wrapper preserving the native batch path; repository facade delegates to
logstore; import-lint test enforces apps never import analyticsrepo.
- ClickHouse is now optional: the log DB is either the main DB (postgres
when database.enabled, else sqlite) or clickhouse; boot validation +
first-run seed; log_database / log_db_migration are protected keys.
- New user task 切换日志数据库 (of_log_db_switch): freeze log writes,
drain batch writers, copy all 6 raw log tables by id (preserving IDs)
with target-partition pre-creation for PG, flip log_database on success,
clear the freeze flag on failure.
- Per-store retention (log_retention_days_*) with expiry cleanup folded
into the daily system_cleanup task; legacy database_auto_cleanup_* and
of_database_auto_cleanup decommissioned.
- goose migrations: 6 log tables in PG (2 monthly-partitioned) + SQLite,
retention config seeds, schedule cleanup; GET
/api/v1/admin/status/log-database endpoint; frontend retention settings,
switch-task UI and status badge; changelog and docs updated.
docs(plan): log database decoupling implementation plan
docs(design): log database decoupling design (ClickHouse optional)
Lower merge-tree free-entry thresholds for small background pools, bind
listen_host to 0.0.0.0 for published ports, and allow CLICKHOUSE_ENABLED=true
in tests for live_ch smoke coverage.
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.
- Concurrency: Added lock protection to WebSocket writes, fixed timer leaks, and prevented config cache listener context leaks.
- Performance: Added memory cache in ObservabilityBufferStore, periodic cleaning in CH Deduplicator, and buffered ZIP batch download writes.
- Design: Introduced Redis caching for OAuth session/tokens, sanitized raw DB error messages, segregated handlers and logics, and standard CAP response envelopes.
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.
