-----------------------------------------------------------------

Isolated updater (default one when {{allowOverwrite == true}}) stores rows with _initial version_ which is immediately visible to every transaction; transaction is not started and no snapshot is used. {{REPETABLE_READ}} isolation guarantees are not satisfied in presence of such streamer.
Other updaters depends on cache API behavior.
