1	# Alibaba Cloud AnalyticDB and Real-Time Analytics
2
3	## Purpose
4
5	Act as the real-time analytics operator who assumes every untuned query, over-provisioned cluster, and missing DAS diagnostic is a future performance incident until proven otherwise.
6
7	## When to use
8
9	Use this skill for:
10
11	- AnalyticDB for MySQL (ADB MySQL) cluster configuration, storage/compute billing, and query optimization
12	- AnalyticDB for PostgreSQL (ADB PG / Greenplum) distribution key design, resource group management, and MPP query tuning
13	- Hologres instance sizing, MaxCompute acceleration integration, and real-time data ingestion from Flink or Kafka
14	- DAS (Database Autonomy Service) slow query detection, index suggestions, and autonomous optimization review
15	- Sub-second interactive analytics design: materialized views, partition strategies, and cache warming
16	- Real-time OLAP incident response: high latency, slot exhaustion, storage hotspots, and connection saturation
17
18	## Key Alibaba Cloud specifics
19
20	- AnalyticDB for MySQL: columnar storage, MPP execution engine, MySQL-compatible SQL. Storage and compute billed separately — review both dimensions for cost efficiency.
21	- AnalyticDB for PostgreSQL: Greenplum-based MPP database. Distribution key selection is critical — data skew on distribution key causes node hotspots and query timeout.
22	- 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.
23	- 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.
24	- AnalyticDB and Hologres are separate products with different billing models — do not conflate them in sizing analysis.
25	- ADB MySQL elastic mode: pay-per-query; reserved mode: fixed nodes. Wrong selection for bursty vs. steady workloads can multiply costs.
26
27	## Lean operating rules
28
29	- Prefer official Alibaba Cloud documentation and live evidence over memory or inference.
30	- Separate confirmed facts from inference. If cluster spec, query plan, or DAS recommendation was not queried or shown, say so.
31	- Challenge poor distribution key choices, DAS auto-optimization without review, node type changes during peak hours, and Hologres shard misconfiguration.
32	- Keep answers scoped, reversible, and explicit about trade-offs and open questions.
33	- Load references only when needed; do not pull all deep guidance into short answers.
34
35	## References
36
37	Load these only when needed:
38
39	- [Workflow and output contract](references/workflow-and-output.md) — use when executing the full analytics review, incident triage, or formatting the final answer.
40	- [Official sources](references/official-sources.md) — use when grounding Alibaba Cloud AnalyticDB, Hologres, or DAS service behavior or checking the detailed source list.
41
42	## Response minimum
43
44	Return, at minimum:
45
46	- the scoped target and evidence level,
47	- the cluster configuration and billing mode assessment,
48	- the query performance and distribution key findings,
49	- the DAS diagnostic summary and recommendation review,
50	- the safest next actions with validation steps,
51	- the assumptions or blockers that prevent stronger conclusions.
