Abstract
Cache optimization for data preparation includes generating a data traversal program that represents a result of a set of sequenced data preparation operations performed on one or more sets of data. The data traversal program indicates how to assemble one or more affected columns in the one or more sets of data to derive the result. It further includes in response to receiving a specification of the set of sequenced operations to be performed on the one or more sets of data, accessing the data traversal program that represents the result or a stored copy of the data traversal program that represents the result. It further includes assembling the one or more affected columns in the one or more sets of data according to the data traversal program to re-generate the result. It further includes outputting the result.
