A computer implemented method for initializing a secondary database system includes receiving table state information from a primary database system at a secondary database system. The table state information includes information identifying which tables had an open operation during a savepoint event. Metadata associated with the tables is parsed to identify table state information from the metadata and a lock is created for each table identified as having an open operation during the savepoint event. Afterwards, log transaction information is sequentially parsed. Related apparatus, systems, techniques and articles are also described.
