/**
 * A helper class that is used to accumulate messages and add them to {@link YdbTransaction}.
 * Several {@link Message}s or/and {@link tech.ydb.topic.read.events.DataReceivedEvent}s can be accepted to add to
 * {@link YdbTransaction} later all at once.
 * All messages should be read from the same Reader this accumulator was created on.
 * Contains no data references and therefore may also be useful in cases where messages are committed after processing
 * data in an external system.
