ClickHouse now updates the memory limit dynamically at runtime whenever Linux's CGroups memory limit value changes.
Why it matters
This feature addresses the issue where ClickHouse would not adapt to changes in memory constraints imposed by Linux CGroups after startup, ensuring that memory usage limits are respected dynamically without needing to restart the server.How to use it
This feature is enabled automatically; ClickHouse monitors Linux CGroups for memory limit changes and updates its internal memory limits in real-time without requiring any manual configuration.
