[zhujt20]

set ttl to root.__audit.log.** if audit_log_ttl_in_days is set.

[Copilot]

Pull Request Overview

This PR implements TTL (Time To Live) functionality for audit log data by adding a configurable audit_log_ttl_in_days parameter. When set to a positive value, it automatically applies TTL to the audit log device path root.__audit.log.** to enable automatic cleanup of old audit logs.

• Adds audit_log_ttl_in_days configuration parameter to CommonConfig
• Implements TTL setting logic in DNAuditLogger when audit logs are initialized
• Converts TTL from days to milliseconds for the SET TTL statement

The hardcoded magic numbers (24, 3600, 1000) for time conversion should be replaced with named constants or use TimeUnit for better readability and maintainability. Consider using TimeUnit.DAYS.toMillis(auditLogTtlInDays) instead.

[Copilot]

The TTL setting operation should check the result status to ensure it was successful. If the TTL setting fails, it could lead to unexpected behavior where audit logs are not cleaned up as expected.
