- **SQL Server** (`Driver.Historian.SqlServer`): `hist.Sample` PK `(TagId, SourceTimeUtc)` — writes are insert-if-absent, so outbox redelivery is idempotent. Stores every value kind with its **real status**; per-sample aggregates (10, simple definitions) are pushed down to T-SQL with bucket math in **100 ns ticks**; the Part 13 time-weighted seven (TimeAverage/TimeAverage2/Total/Total2/Interpolative, #671 — ⚠️ `Total` is now the time-weighted integral, no longer `SUM` — plus the **duration-based** PercentGood/PercentBad, #680) stream window + 4 bound rows into the shared `TimeWeightedAggregator` (both SQL backends, identical results; reverse `Interpolative` anchored at the later time; window capped by `ServerHistorian:MaxTimeWeightedRawRows` ⇒ `BadTooManyOperations`, percentages included). ⚠️ **#680 status rules (client-visible):** TimeAverage/Total are Uncertain if any part of the interval uses an Uncertain value, is bridged across a Bad sample, is extrapolated past the last sample (⇒ a live tag's latest interval is Uncertain) or is not covered; TimeAverage2/Total2 keep the SDK time-based rule (Uncertain time counts as Good) but never extrapolate past the last sample — that interval is Partial, later ones `BadNoData` (a report-by-exception tag with nothing after its last sample reads `BadNoData` until its next sample arrives). `docs/Historian.md` §"Time-weighted aggregates". ⚠️ **#680 per-sample (client-visible):** `Count` counts **Good** samples only (value-based status; an all-Bad interval is generic Bad, value null) and an empty interval **inside the tag's data range** is `0`/Good (outside it still `BadNoData`); `Start`/`End` return the **raw** first/last sample of any quality — its own timestamp and status, value null when Bad; `Delta` is Uncertain only when the interval's first or last sample is unusable; and every per-sample aggregate but `Average` sets **end-of-data Partial** on the interval holding the last sample (forward incl. its earlier edge, reverse strictly inside), never on a Bad result. The data-range lookup is a seek on SQL Server but a partition scan on QuestDB (unindexed `tag` SYMBOL). `docs/Historian.md` §"Aggregates". Docker-dev recipe, schema and aggregate semantics: `docs/Historian.md` §"SQL Server backend". Integration tests need `HISTORIAN_SQL_TEST_CONNECTION`. **Retention (#667):** opt-in `SqlServer:RetentionDays` (+ `PurgeInterval` 1h, `PurgeBatchSize` 4000) -> `HistorianRetentionService` purges old `hist.Sample` (per tag) / `hist.Event` in `DELETE TOP(n)` batches, Primary-gated on `IHistorizationRoleView`, one purger per DB via `sp_getapplock`; counter `otopcua.historian.retention.purged{table}`. Optional `IHistorianBackendProvider.CreateRetention` (default null). `docs/Historian.md` §Retention.

- **QuestDB** (`Driver.Historian.QuestDb`, `ServerHistorian:QuestDb:*`, Npgsql over PG wire; docker-dev overlay `docker-compose.questdb.yml`): same kinds/status/aggregates/HistoryUpdate as SqlServer, soft delete by tombstone (INSERT only — never `UPDATE`/`DELETE`; every read filters `NOT deleted`). ⚠️ **Timestamps are µs** (`QuestDbConnection.Round`/`BindTimestamp`; `IHistorianDataSource.TimestampResolutionTicks` = 10 steps HistoryRead paging), **pre-1970 cannot be stored** (writer drops, HistoryUpdate `BadOutOfRange`), every write waits for WAL visibility, TTL is enforced on write commits only, set Npgsql `Maximum Pool Size` < QuestDB's 64. `docs/Historian.md` §"QuestDB backend".
|
||||
- ⚠️ **Reverse processed reads are Part 13/SDK-anchored (#677, client-visible):** every aggregate on SqlServer/QuestDB now anchors a reverse read at its later time — window `(end, start]`, partial interval earliest, each stamped with its later edge (was: earlier-anchored, stamped earlier edge); on forward reads Partial also marks the interval the data starts inside (not Average — the SDK's rule, forward-only); a non-default client `AggregateConfiguration` ⇒ `BadAggregateConfigurationRejected`; Gateway provisioning sends `IntegralDivisor = 1`. SDK-parity tests: `SdkAggregateParityTests`. `docs/Historian.md` §Aggregates.
|
||||
- **Advertised aggregates (#682):** `IHistorianDataSource.SupportedAggregates` (Gateway 4 via `GatewayHistorianDataSource.ServedAggregates`, SqlServer/QuestDB 17 via `AggregateFamilies.Served`, Null **none**; a null set ⇒ all) is the one authority for `HistoryServerCapabilities/AggregateFunctions` (i=11201 — only its folder references are trimmed) and the up-front `BadAggregateNotSupported` in HistoryRead-Processed. ⚠️ `ServerCapabilities/AggregateFunctions` (i=2997) is deliberately NOT trimmed: it keeps the SDK's 37 because live `AggregateFilter` subscriptions still compute them all. ⚠️ Historian disabled ⇒ Processed is now `BadAggregateNotSupported`, not `GoodNoData`. `docs/Historian.md` §Advertised aggregates.
|
||||
- **Real status fix:** the recorder used to stamp every sample Good (`192`); it now carries the driver's status. ⚠️ On the **Gateway** backend this changes nothing stored: the gateway discards quality (C-002), so AVEVA still stores Good.
|
||||
- **Comms loss is historized as an outage marker** (`Empty` + `BadNoCommunication`, one per tag per outage) on SqlServer; dropped (`DroppedUnsupportedKind`) on Gateway. Outbox records are **format v2** — drain or delete `ContinuousHistorization:OutboxPath` before downgrading a node.
|
||||
- **HistoryUpdate** (SqlServer + QuestDb; Gateway ⇒ `BadHistoryOperationUnsupported`): Insert/Replace/Update/DeleteRaw/DeleteAtTime, **Primary-only** since #674 (off-Primary ⇒ `BadInvalidState`, after authorization AND after planning — an unservable request (Remove / `IsDeleteModified` / not historized) stays `BadHistoryOperationUnsupported` off-Primary; the verdict is `IHistoryUpdateRoleView` = the data-plane verdict but **closed until this node's first redundancy snapshot**, so a pair cannot both accept in the boot window; admin-only nodes register no view ⇒ no gate; reads ungated), items with a `SourceTimestamp` past now + `ServerHistorian:HistoryUpdateMaxFutureSkew` (default 1 day, ≤0 disables) ⇒ `BadOutOfRange` in the node manager (every backend), gated in both ACL modes — flag off needs the `HistoryUpdate` role from a **Cluster-scoped** grant (+ key re-check), flag on uses `DataPlaneAuthorizer`'s HistoryUpdate operation; `WriteOperate` never implies it. The `HistoryWrite` AccessLevel bit is set only when an updater is wired at materialise time. `docs/Historian.md` §HistoryUpdate, `docs/security.md`. ⚠️ **SqlServer schema v1 is accepted (#674)** with `AutoCreateSchema=false`: writes/reads/events/retention work; modified reads + HistoryUpdate ⇒ node-level `BadHistoryOperationUnsupported` on every arm (the updater throws `NotSupportedException`, nothing sent; the `HistoryWrite` bit is still advertised — not knowable at materialise time), retention skips `SampleModified`, one Warning per boot (`SqlServerSchemaBootstrapper.SupportsModifiedTrail`; `RequiredVersion` = 1, `ModifiedTrailVersion` = 2). QuestDB: keep `cairo.ttl.use.wall.clock=true`; a QuestDB trail INSERT retried after a client timeout duplicates (no DEDUP key).

### Advertised aggregates (`AggregateFunctions`, #682)
|
||||
|
||||
Each backend declares the aggregates it serves as `IHistorianDataSource.SupportedAggregates` — **the single authority** for
|
||||
two things:
|
||||
|
||||
- **What the server advertises as HISTORY aggregates.** `HistoryServerCapabilities/AggregateFunctions` (`i=11201`) lists
|
||||
exactly that set. Before #682 it listed the SDK's full 37 regardless of backend.
|
||||
- **What HistoryRead-Processed refuses up front.** An aggregate outside the set is `BadAggregateNotSupported` for that node
|
||||
without a backend call (the backend still throws `HistoryAggregateNotSupportedException` for one as defence in depth —
|
||||
derived from the same table, never a second list). A source whose `SupportedAggregates` is `null` (out-of-tree, against
|
||||
the contract) is treated as the interface default — **all** — by both consumers.
|
||||
|
||||
⚠️ **`Server/ServerCapabilities/AggregateFunctions` (`i=2997`) is deliberately NOT trimmed** — it keeps the SDK's full 37 in
|
||||
every configuration, including with no historian. Part 5 defines it as every aggregate the *server* supports, and the server
|
||||
still computes all of them for live data: a MonitoredItem `AggregateFilter` is validated and computed by the SDK's
|
||||
`AggregateManager`, not the historian. The SDK models the same split (`DiagnosticsNodeManager.AddAggregateFunction` always adds
|
||||
to i=2997 and to i=11201 only for historical aggregates). The two are separate folder nodes organizing the same
|
||||
aggregate-function objects. A client choosing a history aggregate should read **i=11201**.
|
||||
|
||||
| `ServerHistorian:Backend` | i=11201 (history) | i=2997 (server) | Declared by |
|
||||
|---|---|---|---|
|
||||
| `Gateway` | 4 — TimeAverage, Minimum, Maximum, Total | all 37 | `GatewayHistorianDataSource.ServedAggregates` (today `AggregateModeMapper.Served`, derived from its mapping switch) |
|
||||
| `SqlServer`, `QuestDb` | 17 — the [aggregate table](#aggregates-processed-reads) | all 37 | `AggregateFamilies.Served` (Sql.Common; every member with a family) |
|
||||
| historian disabled (Null source) | **none** | all 37 | `NullHistorianDataSource` |
|
||||
|
||||
⚠️ **Client-visible: with no historian configured a processed HistoryRead is now `BadAggregateNotSupported`, not
|
||||
`GoodNoData`.** An aggregate is a statistic the server cannot compute without a history, and the empty i=11201 now says so;
|
||||
Raw / AtTime / Events reads on the Null source still return the empty `GoodNoData` result.
|
||||
|
||||
How it is wired: `OtOpcUaSdkServer` keeps the SDK's `CreateAggregateManager` (all 37 calculator factories) and then trims
|
||||
only the i=11201 ⇄ aggregate `Organizes` references (both directions) to the node manager's current source — the Null
|
||||
default at boot; the Host's `SetHistorianDataSource` (the backend resolved once from `ServerHistorian:Backend`) re-syncs it
|
||||
right after start, and every later assignment re-syncs both ways. ⚠️ **The calculator factories are deliberately NOT
|
||||
removed**: live aggregate subscriptions keep working for every SDK aggregate (pinned over the wire by
|
||||
`AdvertisedAggregateFunctionsWireTests`). The aggregate-function object nodes themselves stay readable. A boot log line
|
||||
names the advertised history set.
|
||||
|
||||
⚠️ **Boot window.** `SetHistorianDataSource` runs right after the SDK server has started (`OtOpcUaServerHostedService.StartAsync`),
|
||||
so for the few milliseconds between the endpoint opening and that call i=11201 is empty and a processed HistoryRead is
|
||||
refused `BadAggregateNotSupported` — the Null default's answer. A client that browses i=11201 in that window sees an empty
|
||||
list; re-browse after connect if it matters.
|
||||
|
||||
Not changed: the `HistoryServerCapabilities` booleans (`AccessHistoryDataCapability`, `InsertDataCapability`, …) are still
|
||||
whatever the SDK sets — #682 touches only the i=11201 folder (follow-up candidate).
