### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Description | Operation Type | Table Type | Effect of `enable_file_cache` | Effect of `disable_file_cache` | | :--- | :--- | :--- | :--- | | **Write (Load)** | **Internal Table** | **None**<br>(Ignored) | **Controls Write-to-Cache**<br>(True = Do not write to cache<br>False = Write to cache) | | | **External Table** | **None**<br>(Ignored, writes directly to remote storage) | **None**<br>(Ignored, writes directly to remote storage) | | **Read (Query)** | **External Table** | **On/Off Switch**<br>(True = Use cache<br>False = Read directly from remote) | **Disposable Flag**<br>(Used when cache is enabled. Determines if data is "one-time use") | | | **Internal Table** | **Ineffective**<br>(Always uses cache if globally enabled in BE) | **Eviction Policy Control**<br>(True = Uses disposable queue [TTL/LRU]<br>False = Uses normal queue) | [2026-01-04 fe enable_file_cache和disable_file_cache对缓存读写操作影响分析.pdf](https://github.com/user-attachments/files/24420608/2026-01-04.fe.enable_file_cache.disable_file_cache.pdf) ### Solution The parameter enable_file_cacheis currently not utilized for internal tables; only datalake tables are making use of it. If internal tables could leverage this functionality, the role of disable_file_cacheshould be transferable to them as well. ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
