Claim 6:
7. The system of claim 6, wherein decompressing the first column comprises:
accessing a compressed value for each entry in the first micro-partition for the first column;
accessing a dictionary that maps compressed values to uncompressed values; and
using the dictionary, determining the uncompressed value for each compressed value of the entries in the first micro-partition;
the operations further comprise:
providing, in response to the operation for the table, the compressed value for the first column for each entry in the decompressed rows of the first micro-partition; and
wherein the aggregating of the entries in the table to create the first aggregated data structure determines to combine a first entry with a second entry based on the compressed value of the first entry being identical to the compressed value of the second entry.
