Query all PersistentActor
identifiers, i.e.
Query all PersistentActor
identifiers, i.e. as defined by the
persistenceId
of the PersistentActor
.
The stream is not completed when it reaches the end of the currently used persistenceIds
,
but it continues to push new persistenceIds
when new persistent actors are created.
Corresponding query that is completed when it reaches the end of the currently
currently used persistenceIds
is provided by CurrentPersistenceIdsQuery#currentPersistenceIds.
A plugin may optionally support this query by implementing this interface.
