MEP: Add collection level auto compaction config

Current state: In Progress

ISSUE: [Enhancement]: Support collection level config to disable auto-compaction #23993

Keywords: Collection, Compaction, Config

Released: N/A

Summary

Compaction has a config item to control whether auto-compaction is enabled or not. This configuration is global and impacts all collections in system.

In some scenarios, we might want to control the granularity of auto-compaction switch so that it could be achieved that:

• Disable auto-compaction during importing data to prevent rebuilt indexes
• Disable auto-compaction during some test cases to make system behavior stable

Design

Add collection level attribute, attribute key is "collection.autocompaction.enabled"(see also pkg/common/common.go).

While handling all compaction signal, check collection level configuration:

• If not set, use global auto-compaction setting
• If config is valid, use collection level setting
• If config value is invalid, fallback to global setting

How to change this setting

All collection-level attribute could be changed by AlterCollection API

Test Plan

Unit tests

Add unit tests for collection level auto compaction switch.

E2E Tests

Change some case to disable collection auto compaction to rectify test case behavior.

Integration Tests
