21. COMMUNITY DAY Mumbai Choosing AWS AppSync Protocol HTTPs, WebSocket API Type GraphQL Security API keys, IAM, Cognito Caching Simple caching option available Offline capability Supported with AppSync resolvers and SDK Integration type Data Sources - REST APIs, Lambda functions, AWS Services API operation GraphQL operations - Query, Mutation and Subscription Direct integration with AWS services with transformation AppSync resolvers with VTL and JS runtime - both unit resolvers and pipeline resolvers Throttling and rate-limits Limited throttling options for the APIs
