Abstract: An approach is provided for detecting a data discrepancy in a replication pipeline. During a live data replication process that includes moving logical records in the replication pipeline from a source database to a target database via component(s), a raw record is read from a log entry. A logical record is obtained by converting the raw record. The logical record is moved in the replication pipeline so that a next component receives the logical record. Responsive to obtaining or receiving the logical record, metadata is updated in sorted hashmaps. A data discrepancy is detected between the obtained logical record and the moved logical record by analyzing the updated metadata.

Abstract: Embodiments generally relate data replication in databases. In some embodiments, a method includes accessing transaction information from a staging store at a first database. The method further includes determining one or more records to be prefetched from a hard disk of a second database based on the transaction information. The method further includes prefetching the one or more records to be prefetched from the hard disk. The method further includes storing the one or more prefetched records in a memory of the second database. The method further includes updating the one or more records stored in the second database based on the transaction information.
