Description
The default IsolationLevel used by interactive queries. Only meaningful when enable.transactional.statestores is true: READ_UNCOMMITTED reads include writes staged in the transaction buffer since the last commit; READ_COMMITTED reads skip the transaction buffer and return only committed data. IQv1 queries always use this value. IQv2 queries use this value as a default, but can override it per-query.
