Cache is an in-memory cache for storing aggregate and process instances for a single handler.
func (*Cache) Acquire ¶
Acquire locks and returns the cache record with the given ID, and ties its lifetime to w.
The lock on the record is automatically released when w is completed. The record is removed from the cache if w fails.
If the record has already been acquired, it blocks until the record is released or ctx is canceled.
