DATABASE SYSTEM UTILIZING PROBABILISTIC INDEXING
A database system operates by: storing a plurality of variable-length data of a column of a plurality of rows; storing a plurality of fixed-length index values of a probabilistic indexing scheme for the column; and identifying a filtered subset of the plurality of rows having variable-length data of...

| description | A database system operates by: storing a plurality of variable-length data of a column of a plurality of rows; storing a plurality of fixed-length index values of a probabilistic indexing scheme for the column; and identifying a filtered subset of the plurality of rows having variable-length data of the column equal to a given value based on: identifying a first subset of rows as a proper subset of the plurality of rows based on the plurality of fixed-length index values; and comparing the variable-length data of only rows in the first subset of rows to the given value to identify the filtered subset as a subset of the first subset of rows. |
