## What - Add Chinese and English usage guides for external metadata cache memory management, supported from Doris 4.1.5. - Document FE-, Catalog-, and cache-entry-level memory limits and their configuration hierarchy. - Cover the supported Hive, Iceberg, and Paimon cache entries, configuration examples, eviction behavior, and operational guidance. - Add the guide to the 4.x sidebar and link it from the metadata cache page. - Clarify that Hive cache properties are reloaded from Doris 4.1.5 by rebuilding the affected Catalog cache. ## Why This documents the user-facing configuration and runtime behavior introduced by apache/doris#66717, especially the cases discussed during review: - A Catalog or cache-entry limit can be configured without an FE-wide limit. - Oversized or safely unmeasurable objects are returned to the query but are not cached; cache admission does not fail the query. - Shared infrastructure such as Catalog, FileIO, and thread pools is excluded from a single cache entry's ownership. - Only explicitly supported cache entries accept `max-weight`; unsupported keys are rejected instead of being silently ignored. ## Checks - `git diff --check` - Parsed the 4.x sidebar JSON and both document frontmatters. - Verified balanced Markdown code fences and a single sidebar entry. A full Docusaurus build was not run because dependencies are not installed in the clean worktree. -- This is an automated message from the Apache Git Service.
