METHODS AND SYSTEMS FOR PERFORMING A VECTORIZED DELETE IN A DISTRIBUTED DATABASE SYSTEM: abstract simplified (18334913)

• This abstract for appeared for patent application number 18334913 Titled 'METHODS AND SYSTEMS FOR PERFORMING A VECTORIZED DELETE IN A DISTRIBUTED DATABASE SYSTEM'

Simplified Explanation

This abstract describes techniques for clustering delete targets in a distributed database system. The goal is to efficiently delete files by grouping them into clusters based on certain constraints. The process involves retrieving a file to be deleted from a set of delete targets, scanning existing clusters of files marked for deletion to find clusters with similar constraints, and either adding the file to an existing cluster or creating a new cluster if no suitable cluster is found. Additionally, a delta array is generated for each file in the new cluster, which represents data items in the file and indicates which data items should be deleted based on a deletion signal.

Original Abstract Submitted

Example aspects include techniques for clustering delete targets for vectorized deletion including retrieving, from a set of delete targets in a distributed database system, a file to be deleted, scanning existing clusters of files marked for deletion to identify at least one existing cluster of files having constraints corresponding to the file, based on identifying the at least one existing cluster of files, adding the file to the at least one existing cluster of files to create a new cluster of files, based on failing to identify the at least one existing cluster of files, creating the new cluster of files including the file, and generating, for each file in the new cluster of files and based on a deletion signal, a delta array including multiple bits representing data items in each file and indicating, based on bit value, target data items to be deleted from each file.
