Amazon Athena

DE//AGENT currently lists 3 resources under Amazon Athena: 1 skill, 1 template, 1 project. Everything below is derived from the live registry — counts, capabilities, verification state and security posture come from the curated records, never from marketing copy.

Documented learning objectives across these resources:

• Read the scanned-bytes metric per query — via Athena Partition Advisor
• Apply partition projection for high-cardinality columns — via Athena Partition Advisor
• Compact small files to cut per-request overhead — via Athena Partition Advisor
• Lay out Parquet so Athena prunes well — via S3 → Glue → Athena
• Use partition projection instead of repeated crawls — via S3 → Glue → Athena
• Measure and cut bytes scanned — via S3 → Glue → Athena

These resources map to stage: Cloud (3). Follow the four-phase roadmap to place this topic inside a progression instead of learning it in isolation.

Every entry, its shape and its trust state — sorted by the registry's composite score. This table is the honest version of a marketing comparison: no sponsored placements, no unverifiable claims.

How scores are computed: source quality score.

Highest composite score first:

1. Athena Partition Advisor score 33.4 — intermediate
2. S3 → Glue → Athena score 30.15 — intermediate
3. Terraform AWS Data Platform score 25.6 — advanced

Scores rank provenance, completeness and trust — read how verification works before adopting anything.

Reach for these with production experience: Terraform AWS Data Platform.

Security-flagged entries: Athena Partition Advisor (3 flags), S3 → Glue → Athena (5 flags), Terraform AWS Data Platform (5 flags). Flags mean the record declares capabilities like credential use or write access — read the security posture on each page before connecting.

• Athena Partition Advisor — Recommends partition projection, bucketing or file-layout changes to reduce Athena bytes-scanned, and writes the projection DDL. details
• S3 → Glue → Athena — A serverless, query-in-place pattern: land Parquet in S3, catalogue it with Glue, and query with Athena while keeping scanned bytes (and cost) low. details
• Terraform AWS Data Platform — S3 buckets with lifecycle + encryption, Glue catalogue, IAM roles scoped to least privilege, and Athena workgroups with query limits. details

Real install commands from the registry — read the source before running any of them:

npx de-agent-platform add athena-partition-advisor

Athena Partition Advisor — review first

amp template new de-agent/terraform-aws-data-platform ./infra

Terraform AWS Data Platform — review first
