When you create a function, you will see that a host.json file is automatically created. While initially empty, it is a global configuration file that defines how triggers and function will behave. Here, you can find an example file with most features, such as bindings' configuration and generic features, available:
{ "aggregator": { "batchSize": 1000, "flushTimeout": "00:00:30" }, "applicationInsights": { "sampling": { "isEnabled": true, "maxTelemetryItemsPerSecond" : 5 } }, "eventHub": { "maxBatchSize": 64, "prefetchCount": 256, "batchCheckpointFrequency": 1 }, "functions": [ "QueueProcessor", "GitHubWebHook" ], "functionTimeout": "00:05:00", "healthMonitor": { "enabled": true, "healthCheckInterval": "00:00:10", "healthCheckWindow": ...
