v.20.7New Feature
Added system.crash_log table for collecting fatal error stack traces
Added system.crash_log table into which stack traces for fatal errors are collected. This table should be empty. #12316 (alexey-milovidov).Why it matters
This feature provides a centralized location for logging stack traces of fatal errors, helping users and developers to diagnose and troubleshoot crashes more effectively by examining the error context directly within ClickHouse.How to use it
Users can query thesystem.crash_log table like any other system table to view stack traces of recent fatal errors. The table is designed to be empty under normal operation and populates only when fatal errors occur.
