Abstract:
A method for table data processing includes retrieving, by at least one hardware processor, first table data associated with a first table version from a plurality of partitions of a storage device. The method further includes detecting, by the at least one hardware processor, an executed transaction causing a modification to the first table data resulting in a second table data associated with a second table version. The second table data is modified to include partition metadata. The partition metadata includes table version information with a mapping of the first table version and the second table version to a plurality of transactions associated with generating the first table data and the second table data.
