US Patent 11016954 Distributed data set extraction for migration

Distributed extraction of data for migration may be implemented for migrating data sets from a first data store to a second data store. Assignments may be determined for different migration agents to obtain and store the data set in the second data store along with a format for storing the assigned data set portions. The migration agents may then be caused to obtain the assigned portions and store the assigned portions in the second data store according to the identified format. Further operations to request or direct the ingestion of the data set from the second data store may be performed by migration agents with respect to a third data store that performs data ingestion.
