Abstract: Methods, systems, and computer-readable media are provided for accessing a plurality of log records describing a plurality of prior transactions and separating the plurality of log records into sequential segments of log records. A synchronization data structure is generated that constrains execution of a first transaction of a first segment until after at least a second transaction of the first segment based at least in part on a stored indication, in the synchronization data structure. The first transaction of the first segment is executed at least in part by accessing the synchronization data structure to constrain playback of the first transaction until after the second transaction. The resulting values are regenerated by executing other transactions of the sequential segments. The regenerated resulting values are stored as a replacement set of data and data management service access is provided to the replacement set of data.
