Summary: | Signature-based cache optimization for data preparation includes: performing a first set of sequenced data preparation operations on one or more sets of data to generate a plurality of transformation results; caching one or more of the plurality of transformation results and one or more corresponding operation signatures, a cached operation signature being derived based at least in part on a subset of sequenced operations that generated a corresponding result; receiving a specification of a second set of sequenced operations; determining an operation signature associated with the second set of sequenced operations; identifying a cached result among the cached results based at least in part on the determined operation signature; and outputting the cached result. |
