Compression of blbs (Specifically rtf and text) & Optimization |
Sat, Dec 15 2007 5:34 PM | Permanent Link |
Herb (Kraft) | I have several tables that contain RTF, DOC or text in compressed blobs. (Latest Ver 4).
As compression worksm more or less, but using redundancy to build trees, etc. Is each blob entry individually compressed? As these are programs for businesses, typically the blobs are going to have many "talked to Client..." etc. If the table is optimized, is the compression recalculated using the entire blob to create the redundancy lists/dictionaries? I'm trying to determine if I should automate optimization to save space (space often important in these applications) Thanks. Herb (Kraft) |

The organization of the data on disk is separate from how the data is compressed prior to the storage layer. -- Tim Young Elevate Software www.elevatesoft.com |
