Properties
| Property | Type | Description |
|---|---|---|
| childProcess | boolean | If true, create a child process to isolate user code from faast scaffolding. Default: true. |
| concurrency | number | The maximum number of concurrent invocations to allow. Default: 100, except for the local provider, where the default is 10. |
| description | string | A user-supplied description for this function, which may make it easier to track different functions when multiple functions are created. |
| env | { [key: string]: string; } | Environment variables available during serverless function execution. Default: {}. |
| exclude | string[] | Exclude a subset of files included by CommonOptions.include. |
| gc | "auto" | "force" | "off" | Garbage collector mode. Default: "auto". |
| include | (string | IncludeOption)[] | Include files to make available in the remote function. See IncludeOption. |
| maxRetries | number | Maximum number of times that faast will retry each invocation. Default: 2 (invocations can therefore be attemped 3 times in total). |
| memorySize | number | Memory limit for each function in MB. This setting has an effect on pricing. Default varies by provider. |
| mode | "https" | "queue" | "auto" | Specify invocation mode. Default: "auto". |
| packageJson | string | object | Specify a package.json file to include with the code package. |
| rate | number | Rate limit invocations (invocations/sec). Default: no rate limit. |
| retentionInDays | number | Specify how many days to wait before reclaiming cloud garbage. Default: 1. |
| speculativeRetryThreshold | number | (BETA) Reduce tail latency by retrying invocations that take substantially longer than other invocations of the same function. Default: 3. |
| timeout | number | Execution time limit for each invocation, in seconds. Default: 60. |
| useDependencyCaching | boolean | Cache installed dependencies from CommonOptions.packageJson. Only applies to AWS. Default: true. |
| validateSerialization | boolean | Check arguments and return values from cloud functions are serializable without losing information. Default: true. |
| webpackOptions | webpack.Configuration | Extra webpack options to use to bundle the code package. |
