Limit Connection Policy

Introduction

Limit connection policy limits connection attempts within a second because creating a new connection is expensive.

If connection attempts hit more than limitation in specific duration, it will respond PolicyViolationException.

Configuration

key	type	default	description
maximumConnectionsPerSecond	int		Maximum connections which is allowed within a second
action	Action	BLOCK	Action to take if the value is outside the specified range.
throttleTimeMs	int	100	Value to throttle with (only applicable when action is set to THROTTLE).

Action

• BLOCK → when fail, save in audit and return error.
• INFO → execute API with wrong value, save in audit.
• THROTTLE → when fail, save in audit and the request will be throttled with time = throttleTimeMs.
