I have heard also that it helps to keep the table with the blobs having a low number of fields. Like just a primary key and the blob field. Have all your other metadata in a seperate table. Especially if you are going to be occasionally doing queries of just the metadata and don't want to always retrieve the image. Comments?
I am doing some blob storage in Oracle with Cold Fusion. Using some purcha$ed java code to get the image in and out. Anyone else doing coldfusion with mysql blobs? How do you retrieve/display the images? --ja On Tue, 28 Sep 2004, Ed Lazor wrote: > What do you mean "chunked"? > > I figured it would be easier to track about 32,000 images in MySQL than in > files, so I setup a test to see what the performance difference is and if > storing in MySQL would actually work. > > Everything is working and it's a lot easier to keep track of the images in > MySQL.
