v.25.7Improvement

Add ability to parse part's prefix and

Add ability to parse part's prefix and suffix and also check coverage for non constant columns. #83377 (Mikhail Artemenko).
Added support for parsing part prefixes and suffixes in data parts and enhanced coverage checks for non-constant columns in ClickHouse.

Why it matters

This feature improves the robustness of data part handling by allowing ClickHouse to recognize and parse additional metadata in part names through prefixes and suffixes. It also ensures that coverage checks comprehensively handle columns that are not constants, thereby enhancing query accuracy and data integrity.

How to use it

Users can benefit from this feature automatically as part of the improved data part parsing logic. No specific user action is required to enable it, but it applies when managing parts with prefixes/suffixes and when running queries that involve non-constant columns in coverage checks.
