A plurality of records are partitioned into a plurality of splits, wherein each split includes at least a portion of the plurality of records. The split of the plurality of splits is provided to a mapper. The mapper assigns at least a portion the records of the at least one split to a group based on a strata of the assigned records, and filters the records of the group based on a comparison of the weights of the records to a local threshold of the mapper. The mapper updates the local threshold of the mapper by communicating with a coordinator. The mapper shuffles the group to a reducer, where the reducer filters the records of the group based on the weights of the records. The reducer provides a stratified sampling of the plurality of records based on the group."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stratified sampling using adaptive parallel data processing","description":"Stratified sampling of a plurality of records is performed.
