Abstract

A computer implemented method for updating a secondary database includes receiving transaction log information from a primary database system at a secondary database system. The transaction log information comprises a first marker identifying a beginning of an operation comprising a plurality of sub-operations and a second marker identifying an end of the operation. The transaction log information is sequentially parsed, a first marker is identified, and a lock state is created after replaying the first marker to ensure proper serialization of the plurality of sub-operations. The lock state is terminated after replaying the second marker. Related apparatus, systems, techniques and articles are also described.
