If a database state was not verified, say so.</li>\n<li>Challenge missing backup policies, single-node deployments without HA, and database proxy disabled for high-connection workloads.</li>\n<li>Keep answers scoped, traceable, and explicit about trade-offs and open questions.</li>\n<li>Load references only when needed; do not pull all deep guidance into short answers.</li>\n</ul>\n<h2>Key database guidance</h2>\n<ul>\n<li><strong>PolarDB</strong> uses shared distributed storage — adding a read node does not duplicate storage. Read scale-out is instantaneous and cost-efficient.</li>\n<li><strong>PolarDB Global Database Network (GDN)</strong> replicates data across regions with sub-1-second lag. Use for geo-redundant OLTP workloads.</li>\n<li><strong>DAS</strong> provides autonomous diagnostics, SQL execution plan analysis, and optimization recommendations. Always check DAS findings before manual tuning.</li>\n<li><strong>Database Proxy</strong> provides built-in connection pooling and read/write splitting. Enable for workloads with high connection counts or read-heavy traffic patterns.</li>\n<li><strong>PolarDB for Oracle</strong> provides Oracle syntax compatibility but has known gaps in specific PL/SQL packages — verify compatibility before migration.</li>\n<li>RDS supports Multi-AZ deployment for high availability — enable for all production instances.</li>\n</ul>\n<h2>References</h2>\n<p>Load these only when needed:</p>\n<ul>\n<li><a href=\"references/workflow-and-output.md\">Workflow and output contract</a> — use when executing the full DBA review or formatting the final operations output.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when grounding Alibaba Cloud PolarDB/RDS/DAS service behavior or feature claims.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the database type and version,</li>\n<li>the cluster topology and high availability configuration,</li>\n<li>the DAS diagnostic findings summary,</li>\n<li>the backup policy assessment,</li>\n<li>the open questions and risks that must be resolved.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":985,"isText":true},{"path":"references/official-sources.md","sizeBytes":910,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":2370,"isText":true},{"path":"SKILL.md","sizeBytes":3134,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
