Abstract
Example aspects include techniques for performing vectorized delete operations in a distributed database system including clustering multiple files stored in the distributed database system, and generating, for each of the multiple files and based on a deletion signal, a delta array including multiple bits representing the data items in the file and indicating, based on bit value, the target data items to be deleted from the file. Generating, for each of the multiple files, the delta array can include reading at least one second file shard of multiple second file shards before performing a join operation on at least one first file shard of multiple first file shards is completed.
