1. A non-transitory computer-readable media storing computer instructions which when executed by one or more processors of a device cause the device to:
detect a transfer of data from a source to a target;
compare the data transferred from the source to data at the target resulting from the transfer to generate a comparison result, wherein the comparison is made in-memory and includes:
calculating a first hash for each row of the data in the source,
calculating a second hash for each row of the data at the target, and
comparing the first hash of each row of the data in the source to the second hash of each respective row of the data at the target to determine one or more rows of the data in the source that each do not match the respective row of the data at the target, and
finding column level mismatches between the source and the target using the one or more rows of the data in the source that each do not match the respective row of the data at the target; and
based on the comparison result, perform data reconciliation between the source and the target.
