v.1.1.54362New Feature

Enhancements to system.processes Table and SHOW PROCESSLIST: New Columns Added

Official CH changelog text
The system.processes table and SHOW PROCESSLIST now have the is_cancelled and peak_memory_usage columns.
The system.processes table and SHOW PROCESSLIST command have been enhanced with two new columns: is_cancelled and peak_memory_usage.

Why it matters

This feature provides users with more detailed information about currently running queries. The is_cancelled column indicates whether a query has been cancelled, while the peak_memory_usage column shows the maximum memory usage of the query, helping in monitoring and debugging resource consumption.

How to use it

Users can query the system.processes table or execute SHOW PROCESSLIST as usual to see the additional is_cancelled and peak_memory_usage columns without any extra configuration.
