Abstract
An operation on a row of a table of a database is initiated. Thereafter, a multi-version concurrency control (MVCC) object is accessed to identify blocks associated with the row position of the row using bitwise operations. Subsequently, a row state block computed based on the row position of the row is accessed to determine a row state for the row. At least one other block is accessed, based in part on the row state, to obtain at least one timestamp from the computed offset based on the row. Next, the at least one timestamp is stored or retrieved. Related apparatus, systems, techniques and articles are also described.
