Scenarios where issues occur: - TTL with LRU eviction enabled (config::enable_ttl_cache_evict_using_lru = true) - TTL's try_reserve_for_ttl_without_lru encounters a limitation set by config::max_ttl_cache_ratio = 90% - LRU begins the eviction process. However, the amount of eviction is determined solely by the condition !is_overflow(), which does not consider the 90% limitation. This leads to a premature return of a successful reserve, resulting in the overall TTL exceeding the 90% limit. Modification method: For the TTL and LRU eviction quantities, in addition to checking for !is_overflow, the condition must also satisfy the restriction set by config::max_ttl_cache_ratio. ## Proposed changes Issue Number: close #xxx <!--Describe your changes.--> -- This is an automated message from the Apache Git Service.
