Reconnection Policies for Ruby SDK

In networked applications, maintaining a stable connection is critical. The PubNub Ruby Software Development Kit (SDK) controls reconnection with two parameters to help applications recover from temporary network disruptions.

Default behavior

Default behavior: If you do not set custom values, :reconnect_interval and :reconnect_attempts default to 10.

Types of reconnection policies

Pubnub Ruby SDK uses two parameters in reconnection logic: :reconnect_interval (in seconds) and :reconnect_attempts. They are set when initializing a Pubnub::Client instance. By default, their values are 10 and 10.

When the connection is lost, the server logs the warning "Connection lost! Reason: reasons," announces status to subscribers with type Pubnub::Constants::TIMEOUT_ANNOUNCEMENT (:disconnect), waits :reconnect_interval, and tries to reconnect. When reconnected, the client announces to subscribers status type Pubnub::Constants::RECONNECTED_ANNOUNCEMENT (:reconnected).

• Use when: Increase :reconnect_attempts for transient outages; decrease :reconnect_interval for faster retries in reliable networks.
