 | aws_lambda | namespace |  | no | Virtual namespace. This can be useful to virtually group Lithops function workers. The functions deployed by lithops will be prefixed by this namespace. For example you can set it to differentiate between `prod`, `dev` and `stage` environments.  |
 | aws_lambda | runtime_include_function | False | no | If set to true, Lithops will automatically build a new runtime, including the function's code, instead of transferring it through the storage backend at invocation time. This is useful when the function's code size is large (in the order of 10s of MB) and the code does not change frequently |
