tinySQL DBMS daemon (tinysqld)
Part of tinySQL. See the root storage and map-tile sections before deploying this durable server profile.
The enterprise DBMS entry point, separate from cmd/server so the older
HTTP/gRPC API server stays compatible. It opens the OpenEnterprise product
profile, requires durable storage, starts the job scheduler through that
profile, exposes a minimal HTTP DBMS API for DB health, storage, scheduler, WAL
and recovery state, and shuts down gracefully on a signal.

Tilesets
-tiles enables an intentionally public map endpoint for an MBTiles-shaped
table named {tileset} and its optional {tileset}_metadata table:
GET /tiles/{tileset}/{z}/{x}/{y}.{ext}
GET /tiles/{tileset}.json
GET /tiles/{tileset}/metadata
The tile route accepts XYZ coordinates and converts the row to MBTiles/TMS
internally. It sends the appropriate content type/encoding from tileset
metadata, ETags, and Cache-Control headers. Keep it disabled unless needed;
put an authenticating proxy in front when a tileset must not be public.
SQL clients can calculate TileMatrix positions, WMS bounding boxes, and CRS
axis order with TILE_MATRIX_BBOX, TILE_MATRIX_POSITION, WMS_BBOX, and
the CRS identifier functions. See the
geospatial standards guide for supported
profiles and coordinate conventions.
For a tileset larger than memory, use -storage paged_index for the published
tile artifact. See the root MBTiles guide
for the table shape, import/export, and indexing workflow.
HTTP API
Unauthenticated:
GET /healthz— DB health snapshot;503if storage is closed or closing.GET /readyz— readiness plus health;503while not ready or unhealthy.
Authenticated when -auth is set, via Authorization: Bearer <token> or
X-tinySQL-Auth: <token>:
GET /api/status— runtime status, backend stats, DB health.GET /api/analytics/vector— vector-cache analytics (requires-analytics).POST /api/exec,POST /api/queryGET /api/catalog/tablesGET /api/catalog/columns(real table schemas fromsys.columns)GET /api/jobs,GET /api/job-historyPOST /api/jobs/run
SQL request body; POST /api/jobs/run takes name instead of sql:
{
"tenant": "default",
"sql": "SELECT name FROM users",
"timeout_ms": 5000
}
Status responses include a health object:
{
"ok": true,
"storage_mode": "disk",
"scheduler_running": true,
"wal_active": false,
"advanced_wal_active": false,
"recovery": {
"mode": "memory",
"recovered_transactions": 0,
"recovered_operations": 0,
"truncated": false
}
}
