Configuration

Config decides what is recorded about each query. Pass it to install(), and to OTelExporter when you create one yourself:

import polars_telemetry
from polars_telemetry import Config, Redaction

polars_telemetry.install(Config(include_plan=True, redaction=Redaction()))

Option	Default	Effect	Cost
node_metrics	True	Read each node's counters when the query ends: per-node metrics, polars.cpu_ms, the hot node, most diagnostics, and the counters in profiles	Most of the OpenTelemetry exporter's time on large plans
include_plan	False	Put the whole plan and its counters on the span as JSON in polars.plan	Kilobytes per span
call_site	True	Record the file, line and function that ran the query	Under a microsecond
redaction	None	What to mask before any exporter receives a query; see Data and privacy	Small, once per query and setting

Exporter options, such as a file's size limit, are on each exporter's page.
