一覽

FaunaDB is a serverless database: no provisioning, pay-per-request, globally replicated by default. ACID transactions, multi-region consistency, and automatic conflict resolution. Perfect for serverless/Jamstack applications (Netlify Functions, AWS Lambda). Senior FaunaDB architects earn 15-25% premium because they design for geo-distribution and handle edge cases (eventual consistency, network partitions). Learning basics takes 2-3 weeks; mastery takes 6+ months. The skill transfers to other serverless databases (DynamoDB, Firestore) and distributed systems thinking.

什麼是 FaunaDB Serverless

FaunaDB is a serverless, globally-distributed database optimized for modern applications. Unlike traditional databases (you provision capacity, manage clusters), FaunaDB is serverless: pay-per-request, automatic scaling, no infrastructure to manage. Key features: ACID transactions (stronger guarantees than most NoSQL), multi-region replication (data replicated globally by default), and conflict-free eventual consistency (updates replicate automatically without manual conflict resolution). It's the database for Jamstack applications, edge computing, and serverless architectures.

❓ 常見問題

Should I use FaunaDB or DynamoDB?
FaunaDB: ACID, no provisioning, global by default, multi-region. DynamoDB: AWS-managed, pay-per-request, limited query flexibility, no ACID. FaunaDB for complex queries + transactions; DynamoDB for key-value workloads.
What's FQL and should I learn it?
FQL is FaunaDB's query language (like SQL for relational). Unique syntax, takes 1 week to learn. Alternatively, use GraphQL endpoint (easier for API-first development).
How does geo-replication work and do I pay extra?
FaunaDB replicates data across regions automatically. No extra cost, included in plan. Reads from nearest region = low latency globally. Writes replicate to all regions = eventual consistency for geo-distance.
What happens if I exceed my serverless quota?
Requests fail with rate limit error. Scale up to next tier or increase quota. No outages, predictable costs.
Can I do ACID transactions across documents?
Yes, FaunaDB supports multi-document transactions. Useful for foreign key integrity, payments (debit + credit in one tx). Slower than single-document, but safe.
