Abstract
A method includes receiving a data set that includes a plurality of data records, where a data record includes a first data field containing a first fixed length data value and a second data field containing a first variable length data value. The method further includes accessing a compression dictionary for the second data field, where a first entry of the compression dictionary includes a key field storing a first fixed length index value and a value field storing the first variable length data value, and where the key field has a smaller data size than the value field. The method further includes creating a storage data set based on the compression dictionary and sending the storage data set to a storage sub-system for storage, where the first variable length data value of the second data field of the data record is replaced with the first fixed length index value.
