Technical Annotations (45)

Configuration Parameters (7)
GATEWAY_LISTENrecommended: :4566,:80,:443
Enables LocalStack gateway to listen on ports 80 and 443 for ALB-to-API Gateway integration
PROVIDER_OVERRIDE_APIGATEWAYrecommended: next_gen
Uses next-generation API Gateway provider implementation
$context.integration.latency
access logging variable to monitor integration latency duration
integration_timeoutrecommended: >29 seconds for long-running operations
default is 29 seconds; increasing may require throttle quota adjustment
APIGW_ENABLE_NEXT_GEN_WEBSOCKETSrecommended: 1
Enables next-gen WebSocket implementation; fix works with or without this setting
Statisticrecommended: Average
Statistical method for evaluating latency metric
Periodrecommended: 5 minutes
Evaluation period for latency measurements
