- 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.
