Abstract:
1. A method of processing data from a file, comprising: using at least one processor to perform a process, the process comprising: identifying multiple portions of data for a large object (LOB), wherein a portion of the multiple portions corresponds to an identifier that indicates a compression state of the portion, and the compression state includes an uncompressed state, a first compressed state associated with a first compression scheme, and a second compressed state associated with a second compression scheme; compressing the portion for storage in a first compression unit using the first compression scheme when the compression state of the portion indicates the first compressed state; compressing the portion using the second compression scheme for storage in the first compression unit when the compression state of the portion indicates the second compressed state; and storing the portion uncompressed in the first compression unit when the compression state of the portion indicates the uncompressed state, wherein two compression units used for storing the large object have different compression requirements.
