PubSub.BackPressureStrategy

Represents the back-pressure strategy for bounded PubSub values.

When to use

Use to preserve every message for current subscribers when a bounded custom PubSub should make publishers wait for capacity instead of dropping or evicting messages.

Details

Publishers wait when the PubSub is at capacity, so all current subscribers can receive every published message.

Gotchas

A slow subscriber can slow down publishers and other subscribers.

See

• bounded for creating bounded PubSubs with back pressure by default
• DroppingStrategy for dropping new messages when capacity is full
• SlidingStrategy for evicting old messages when capacity is full
