Split data storage into main application DB (config only) and
per-webhook event databases (one SQLite file per webhook).
Architecture changes:
- New WebhookDBManager component manages per-webhook DB lifecycle
(create, open, cache, delete) with lazy connection pooling via sync.Map
- Main DB (DBURL) stores only config: Users, Webhooks, Entrypoints,
Targets, APIKeys
- Per-webhook DBs (DATA_DIR) store Events, Deliveries, DeliveryResults
in files named events-{webhook_uuid}.db
- New DATA_DIR env var (default: ./data dev, /data/events prod)
Behavioral changes:
- Webhook creation creates per-webhook DB file
- Webhook deletion hard-deletes per-webhook DB file (config soft-deleted)
- Event ingestion writes to per-webhook DB, not main DB
- Delivery engine polls all per-webhook DBs for pending deliveries
- Database target type marks delivery as immediately successful (events
are already in the dedicated per-webhook DB)
- Event log UI reads from per-webhook DBs with targets from main DB
- Existing webhooks without DB files get them created lazily
Removed:
- ArchivedEvent model (was a half-measure, replaced by per-webhook DBs)
- Event/Delivery/DeliveryResult removed from main DB migrations
Added:
- Comprehensive tests for WebhookDBManager (create, delete, lazy
creation, delivery workflow, multiple webhooks, close all)
- Dockerfile creates /data/events directory
README updates:
- Per-webhook event databases documented as implemented (was Phase 2)
- DATA_DIR added to configuration table
- Docker instructions updated with data volume mount
- Data model diagram updated
- TODO updated (database separation moved to completed)
