SyncDomainEphemeralState
Companion object SyncDomainEphemeralState
class SyncDomainEphemeralState extends SyncDomainEphemeralStateLookup with NamedLogging with CloseableHealthComponent with AtomicHealthComponent
The state of a synchronization domain that is kept only in memory and must be reconstructed after crashes and fatal errors from the SyncDomainPersistentState. The ephemeral state can be kept across network disconnects provided that the local processing continues as far as possible.
