Automatic content-based append detection

Automatic append includes: identifying, based at least in part on contents of a first data set comprising a first plurality of columns and contents of a second data set comprising a second plurality of columns, a plurality of matching columns and a plurality of non-matching columns. The matching columns comprise one or more columns among the first plurality of columns; and corresponding one or more matching columns among the second plurality of columns. ... Paxata Inc

Automated join detection

Automated join detection includes: identifying a set of one or more candidate joins of a first table and a second table; evaluating a set of one or more quality measures corresponding to the set of one or more candidate joins; obtaining a set of one or more selected joins among the set of one or more candidate joins, the set of one or more selected joins being selected based at least in part on one or more corresponding quality measures; and generating a joined table, including by joining the first table and the second table according to a selected join.. . ...

Step editor for data preparation

Using a step editor for data preparation includes: receiving an indication of a user input with respect to at least some of a set of sequenced data preparation operations on a set of data; generating, using one or more processors, a signature based at least in part on the set of sequenced data preparation operations, references to the set of data, and the user input; using the generated signature to determine whether there exists a cached result associated with the set of sequenced data preparation operations, the references to the set of data, and the user input; based at least in part on the determination, obtaining a data traversal program representing a result associated with the set of sequenced operations, the references to the set of data, and the user input; and providing output based at least in part on the result represented by the obtained data traversal program.. . ... Paxata Inc

Signature-based cache optimization for data preparation

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.. . ... Paxata Inc

Cache optimization for data preparation

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, wherein 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; 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; 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; and outputting the result.. . ... Paxata Inc

Distributed pipeline optimization for data preparation

Distributed pipeline optimization for data preparation includes: receiving a specification of a set of sequenced operations to be performed on a set of organized data; dividing the set of data into a plurality of work portions based on a cost function that is dependent on at least one dimension of the set of data; and distributing the plurality of work portions to a plurality of processing nodes to be processed according to the specification of operations.. . ...
