By default, TiSpark does not collect usage information and share the information with PingCAP. You can enable it by configuring
spark.tispark.telemetry.enable = true in spark-default.conf.
When the telemetry collection feature is enabled, usage information will be shared, including(but not limited to):
- A randomly generated telemetry ID.
- OS and hardware information, such as OS name, OS version, CPU, memory, and disk.
- A part of TiSpark configuration.
To view the full content of telemetry, set the level log4j.logger.com.pingcap.tispark lower than INFO in
${SPARK_HOME}/conf/log4j.properties. And the telemetry content will be saved in the log file.
