| 发明名称 | Resuming big data transformations | ||
| 摘要 | Systems and methods for resuming data transformations, such as broken or otherwise unsuccessful data transformations, are described. In some example embodiments, the systems and methods receive a message that indicates a broken data transformation of a data table between a source database and a destination database, identify a maximum and/or largest and greatest value for a date attribute contained within an index column for all rows of the data table that were successfully loaded to the destination database during the data transformation, and select a group of rows of data of the data table stored in the source database by querying the source database to identify rows that include a value for the date attribute that is greater than the identified value. | ||

| 主权项 | 1. A computerized method, comprising: receiving a message that indicates a broken data transformation of a data table between a source database and a destination database; identifying a value for a date attribute contained within an index column for all rows of the data table representing a largest value of the date attribute from the rows of the data table that were successfully loaded to the destination database during the data transformation such that newer data contained within the index column has a larger value for the date attribute comparative to older data contained within the index column; and selecting a group of rows of data of the data table stored in the source database by querying the source database to identify rows that include a value for the date attribute that is greater than the identified value. | ||
