概要

AWS Redshift is a data warehouse for analytic queries on petabyte-scale data. Columnar storage compresses data 10x; massive parallel query processing (MPP) distributes queries across nodes. You load data from S3 (via COPY), write SQL (compatible with PostgreSQL), get results in seconds. Mastery means understanding distribution keys (avoiding skew), sort keys (for range queries), compression encodings, and cost optimization. Learning path: data warehouse concepts (2 weeks) → Redshift setup (2 weeks) → distribution + sort keys (2 weeks) → optimization + tuning (4 weeks).

AWS Redshift Dataとは

AWS Redshift is a data warehouse built for analytic queries on massive datasets. Columnar storage (stores by column, not row) compresses data 10x. Massive Parallel Processing (MPP) distributes queries across nodes. You load data from S3, write SQL queries (PostgreSQL compatible), and get results fast. Use for: business intelligence, analytics pipelines, historical analysis, data science.

❓ よくある質問

Should I use Redshift or Athena?

Redshift: data warehouse, sustained load, complex queries, fast. Athena: ad-hoc queries, pay-per-scan, no schema. Use Redshift for heavy analytics; Athena for occasional queries.

What's MPP?

Massive Parallel Processing. Redshift distributes query across nodes. Each node processes a shard of data in parallel. Result: 100x faster than single-server.

What's distribution key?

Column used to hash-partition data across nodes. Good: even distribution. Bad: skewed distribution (1 node has 90% data). Choose wisely.

How do I load data?

COPY command from S3. Example: COPY table FROM 's3://bucket/data/' IAM_ROLE 'arn:...'. Redshift parallelizes load across nodes.

Can I query S3 without loading?

Yes, Redshift Spectrum. Query S3 data directly without loading into Redshift. Slower than local, cheaper for occasional access.

How much does Redshift cost?

dc2.large: ~$0.25/hour (~$180/mo). dc2.8xlarge: ~$3/hour (~$2200/mo). Storage included. Reserved instances: 30-70% discount.

Is Redshift suitable for production?

Yes, thousands of companies run analytics on Redshift. Caveats: setup complexity, distribution key mistakes cause performance issues.
