Add telemetry to `StatementExecutionStatement` + +**File:** `StatementExecution/StatementExecutionStatement.cs` + +The statement-level telemetry methods (`CreateTelemetryContext()`, `RecordSuccess()`, `RecordError()`, `EmitTelemetry()`) follow the same pattern for both Thrift and SEA. Move these into `TelemetryHelper` as well: + +```csharp +internal static class TelemetryHelper +{ + // ... connection-level methods from above ... + + // Shared statement telemetry methods + public static StatementTelemetryContext?

Populate Missing System Configuration Fields + +**File:** `DatabricksConnection.cs` - `BuildSystemConfiguration()` + +```csharp +// Add to BuildSystemConfiguration() +RuntimeVendor = "Microsoft", // .NET runtime vendor +ClientAppName = GetClientAppName(), // From connection property or user-agent +``` + +**Interface:** +```csharp +private string GetClientAppName() +{ + // Check connection property first, fall back to process name + Properties.TryGetValue("adbc.databricks.client_app_name", out string? appName); + return appName ?? Process.GetCurrentProcess().ProcessName; +} +``` + +### 2. Populate auth_type on Root Log + +**File:** `StatementTelemetryContext.cs` - `BuildTelemetryLog()` + +Add `auth_type` string field to TelemetrySessionContext and set it during connection initialization based on the authentication method used. + +```csharp +// In BuildTelemetryLog() +log.AuthType = _sessionContext.AuthType ?? string.Empty; +``` + +**Mapping:** +| Auth Config | auth_type String | +|---|---| +| PAT | `"pat"` | +| OAuth client_credentials | `"oauth-m2m"` | +| OAuth browser | `"oauth-u2m"` | +| Other | `"other"` | + +### 3. Populate WorkspaceId + +**File:** `DatabricksConnection.cs` - `InitializeTelemetry()` + +Extract workspace ID from server response or connection properties. The workspace ID is available from the HTTP path (e.g., `/sql/1.0/warehouses/` doesn't contain it directly, but server configuration responses may include it). + +```csharp +// Parse workspace ID from server configuration or properties +TelemetrySession.WorkspaceId = ExtractWorkspaceId(); +``` + +### 4. Expand DriverConnectionParameters Population + +**File:** `DatabricksConnection.cs` - `BuildDriverConnectionParams()` + +Add applicable connection parameters: + +```csharp +return new DriverConnectionParameters +{ + HttpPath = httpPath ??

Add Metadata Operation Telemetry + +Currently only `ExecuteQuery()` and `ExecuteUpdate()` emit telemetry.

Track Internal Calls + +**File:** `DatabricksStatement.cs` + +Mark internal calls like `USE SCHEMA` (from `SetSchema()` in DatabricksConnection) with `is_internal_call = true`. + +**Approach:** Add an internal property to StatementTelemetryContext: +```csharp +public bool IsInternalCall { get; set; } +``` + +Set it when creating telemetry context for internal operations. + +### 7. Wire ChunkDetails from CloudFetch to Telemetry + +`SetChunkDetails()` exists on `StatementTelemetryContext` but is never called. The CloudFetch pipeline already tracks per-chunk timing via `Stopwatch` in `CloudFetchDownloader` but only exports it to Activity traces. + +**Approach:** Aggregate chunk metrics in the CloudFetch reader and pass them to the telemetry context before telemetry is emitted. + +```mermaid +sequenceDiagram + participant Stmt as DatabricksStatement + participant Reader as CloudFetchReader + participant DL as CloudFetchDownloader + participant Ctx as StatementTelemetryContext + + Stmt->>Reader: Read all batches + DL->>DL: Track per-chunk Stopwatch + Reader->>Reader: Aggregate chunk stats + Stmt->>Reader: GetChunkMetrics() + Reader-->>Stmt: ChunkMetrics + Stmt->>Ctx: SetChunkDetails(metrics) + Stmt->>Ctx: BuildTelemetryLog() +``` + +**Changes required:** + +#### a.

Track metrics in `CloudFetchDownloader` + +The downloader already has per-file `Stopwatch` timing. Add aggregation fields: +- Record latency of first completed chunk -> `InitialChunkLatencyMs` +- Track max latency across all chunks -> `SlowestChunkLatencyMs` +- Sum all chunk latencies -> `SumChunksDownloadTimeMs` + +Expose via `GetChunkMetrics()` method. + +#### c. Bridge in `CloudFetchReader` / `DatabricksCompositeReader` + +- `CloudFetchReader` already tracks `_totalBytesDownloaded` - add a method to retrieve aggregated chunk metrics from its downloader +- Expose `GetChunkMetrics()` on the reader interface + +#### d. Call `SetChunkDetails()` in `DatabricksStatement.EmitTelemetry()` + +Before building the telemetry log, check if the result reader is a CloudFetch reader and pull chunk metrics: + +```csharp +// In EmitTelemetry() or RecordSuccess() +if (reader is CloudFetchReader cfReader) +{ + var metrics = cfReader.GetChunkMetrics(); + ctx.SetChunkDetails( + metrics.TotalChunksPresent, + metrics.TotalChunksIterated, + metrics.InitialChunkLatencyMs, + metrics.SlowestChunkLatencyMs, + metrics.SumChunksDownloadTimeMs); +} +``` + +**Applies to both Thrift and SEA** since both use `CloudFetchDownloader` under the hood. + +### 8. Track Retry Count + +**File:** `StatementTelemetryContext.cs` + +Add retry count tracking. The retry count is available from the HTTP retry handler. + +```csharp +public int RetryCount { get; set; } + +// In BuildTelemetryLog(): +sqlEvent.RetryCount = RetryCount; +``` + +--- + +## E2E Test Strategy + +### Test Infrastructure + +Use `CapturingTelemetryExporter` to intercept telemetry events and validate proto field values without requiring backend connectivity. + +```mermaid +sequenceDiagram + participant Test as E2E Test + participant Conn as DatabricksConnection + participant Stmt as DatabricksStatement + participant Capture as CapturingTelemetryExporter + + Test->>Conn: Connect with CapturingExporter + Test->>Stmt: ExecuteQuery("SELECT 1") + Stmt->>Capture: Enqueue(telemetryLog) + Test->>Capture: Assert all proto fields +``` + +### Test Cases + +#### System Configuration Tests +- `Telemetry_SystemConfig_AllFieldsPopulated` -

All changes use existing connection properties and runtime information. + +--- + +## Error Handling + +All telemetry changes follow the existing design principle: **telemetry must never impact driver operations**. All new code paths are wrapped in try-catch blocks that silently swallow exceptions. + +--- + +## Concurrency + +No new concurrency concerns. All changes follow existing patterns: +- `TelemetrySessionContext` is created once per connection (single-threaded) +- `StatementTelemetryContext` is created once per statement execution (single-threaded within statement) +- `TelemetryClient.Enqueue()` is already thread-safe
