Added pressure metrics to ClickHouse asynchronous metrics to provide better insight into system load and backpressure conditions.
Why it matters
This feature introduces pressure metrics within the asynchronous metrics subsystem of ClickHouse, allowing users to monitor and understand the pressure or backpressure occurring in different components. It helps in identifying bottlenecks and ensuring smoother system performance under high load.How to use it
Users can enable and view the new pressure metrics through the existing async metrics interfaces and tools. No additional configuration is necessary beyond standard metric collection setups.
