Storage and compute billed separately — review both dimensions for cost efficiency.</li>\n<li>AnalyticDB for PostgreSQL: Greenplum-based MPP database. Distribution key selection is critical — data skew on distribution key causes node hotspots and query timeout.</li>\n<li>Hologres: tightly integrated with MaxCompute for accelerated OLAP queries on MaxCompute tables without data movement. Shard count and storage mode (row vs. column) must match query patterns.</li>\n<li>DAS provides autonomous diagnostics — slow query detection, index recommendations, and storage trend analysis. DAS auto-optimization recommendations require explicit approval before execution; autonomous mode can make schema changes.</li>\n<li>AnalyticDB and Hologres are separate products with different billing models — do not conflate them in sizing analysis.</li>\n<li>ADB MySQL elastic mode: pay-per-query; reserved mode: fixed nodes. Wrong selection for bursty vs. steady workloads can multiply costs.</li>\n</ul>\n<h2>Lean operating rules</h2>\n<ul>\n<li>Prefer official Alibaba Cloud documentation and live evidence over memory or inference.</li>\n<li>Separate confirmed facts from inference. If cluster spec, query plan, or DAS recommendation was not queried or shown, say so.</li>\n<li>Challenge poor distribution key choices, DAS auto-optimization without review, node type changes during peak hours, and Hologres shard misconfiguration.</li>\n<li>Keep answers scoped, reversible, 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>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 analytics review, incident triage, or formatting the final answer.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when grounding Alibaba Cloud AnalyticDB, Hologres, or DAS service behavior or checking the detailed source list.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the scoped target and evidence level,</li>\n<li>the cluster configuration and billing mode assessment,</li>\n<li>the query performance and distribution key findings,</li>\n<li>the DAS diagnostic summary and recommendation review,</li>\n<li>the safest next actions with validation steps,</li>\n<li>the assumptions or blockers that prevent stronger conclusions.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":995,"isText":true},{"path":"references/official-sources.md","sizeBytes":653,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":1608,"isText":true},{"path":"SKILL.md","sizeBytes":3693,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
