Adds instrumentation to support tracing exporters ### Tracing Exporters To enable tracing messages to be observed, a tracing exporter needs to be activated. Use either the environment variable `OTEL_TRACES_EXPORTER` or the parameter `adbc.traces.exporter` to select one of the supported exporters. The parameter has precedence over the environment variable. The following exporters are supported: | Exporter | Description | | --- | --- | | `otlp` | Exports traces to an OpenTelemetry Collector or directly to an Open Telemetry Line Protocol (OTLP) endpoint. | | `adbcfile` | Exports traces to rotating files in a folder. | | `console` | Exports traces to the console output. | | `none` | Disables trace exporting. | Note: _The first connection to activate tracing will enable tracing for any later connections that are created in that process._ (This behavior may change in future implementations.) #### File Exporter (adbcfile) Rotating trace files are written to a folder. The file names are created with the following pattern: `apache.arrow.adbc.drivers.bigquery-<YYYY-MM-DD-HH-mm-ss-fff>-<process-id>.log`. The folder used depends on the platform. | Platform | Folder | | --- | --- | | Windows | `%LOCALAPPDATA%/Apache.Arrow.Adbc/Traces` | | macOS | `$HOME/Library/Application Support/Apache.Arrow.Adbc/Traces` | | Linux | `$HOME/.local/share/Apache.Arrow.Adbc/Traces` | Note that once a tracing exporter is activated/enabled - it stays activated until the process exits. -- This is an automated message from the Apache Git Service.
