fetchError() function

Reports a failed cache read at warning level. The caller then falls through to the real method, so a read failure costs latency rather than correctness.

Signature:

export declare function fetchError(logger: ILogger, err: any, key: string, decorator: Function): void;

Parameters

Parameter	Type	Description
logger	ILogger	logger to report through
err	any	error redis raised
key	string	redis key the read targeted
decorator	Function	decorator that attempted the read

Returns:

void
