The present application discloses a method, system, and computer system for providing a dataframe as a service. The method includes (a) receiving, from a client system, one or more hints identifying parameters for source data; (b) executing a plan for a source dataframe including determining whether accessing the source data for the source dataframe is permitted based at least in part on one or more security policies, wherein the plan is based at least in part on the one or more hints; (c) receiving from the client system a business logic pertaining to a transformation to be applied to the source dataframe; and (d) providing to the client system information pertaining to an execution result obtained based at least in part on the business logic.

Data security for dataframes as a service

A system for processing database data includes an interface and a processor. The interface is configured to receive a query for the database data comprising a date range and a data selection criterion. The processor is configured to determine a set of fields of the database data corresponding to a most recent date of the date range; determine a subset of the set of fields of the database data specified by the data selection criterion; determine a set of transformations, where each transformation of the set of transformations corresponds to a field of the subset and a sub-range of the date range; transform the database data to determine transformed database data using the set of transformations; and select data from the transformed database data using the data selection criterion to determine a query response.

Efficient data processing for schema changes

A system for determining percentiles includes an interface and a processor. The interface is configured to receive a request to determine a percentile value. The processor is configured to determine relevant data based at least in part on the request, determine an ordered data list map, determine the percentile value based at least in part on the ordered data list map, and provide the percentile value.

Percentile determination system

A system for determining percentiles for a performance data includes an interface configured to receive a request to determine a percentile value for the performance data and a processor configured to determine relevant data based at least in part on the request, determine an ordered data list map, determine the percentile value based at least in part on the ordered data list map, and provide the percentile value for the performance data.
