Traces Exporters
FileExporter
Provides an OpenTelemetry (OTel) exporter to write telemetry traces to
rotating files in folder. File names are created with the following pattern:
<trace-source>-<YYYY-MM-DD-HH-mm-ss-fff>-<process-id>.log.
For example: apache.arrow.adbc.drivers.databricks-2025-08-15-10-35-56-012345-99999.log.
The default folder used is:
| 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 |
By default, up to 999 files of maximum size 1024 KB are written to the trace folder.
ExportersBuilder
Helps activate one of a dictionary of supported exporters.
The environment variable OTEL_TRACES_EXPORTER can be used to select one of the
available exporters. Or the database parameter adbc.traces.exporter can be used,
which 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. |
