Do you recommend using two tables or one? With one table, it can look something like this.
class Image data = blobField width = Int height = Int with two tables class ImageInfo width = Int height = Int image = refToImage class Image data = blobField Advantages with one table: One query to get both the dimension and its blob. Disadvantages Wasting bandwidth if you're only interested in the dimension. Unless you have a way of lazyloading the blob. The dimension can cut into the 1MB size limit of the document. Advantage of two tables: Don't have to load the blob if you only want the dimension. The blob can use the full 1MB size limit. Disadvantage. Need to perform two queries if you want both the dimension and the blob. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
