v.25.5Improvement

Calculate the relevant fields

Official CH changelog text
Calculate the relevant fields for query 'SHOW CLUSTER <name>' instead of all fields. #79368 (Tuan Pham Anh).
Optimize the SHOW CLUSTER <name> query to calculate only relevant fields instead of all fields, improving performance.

Why it matters

The feature addresses inefficiency in the SHOW CLUSTER <name> command by limiting calculations to only necessary data fields. This reduces computational overhead and improves response times for users querying cluster information.

How to use it

Simply use the SHOW CLUSTER <name> SQL command as usual. The optimization is applied internally with no change in syntax or additional parameters required.
