Claim 13:
14. A storage system comprising:
a storage apparatus;
a memory; and
a processor that controls data input and output, wherein
the memory stores dimension setting information, which is information representing an attribute for each of data dimensions of a multidimensional dataset,
the processor performs compressor generation processing, which is processing for generating a compressor based on the dimension setting information,
the processor performs write processing,
the write processing is processing for compressing a write target multidimensional dataset using the generated compressor and writing compressed data in the storage apparatus, and
the processor analyzes statistics of an input multidimensional dataset, specifies a number of data dimensions and an attribute for each of the data dimensions based on a result of analysis, and creates or updates the dimension setting information based on the specified number of data dimensions and the specified attribute for each of the data dimensions.
