CLZ Mobile App (IOS) Image Sync Bugs (Image Sync Inefficiency)

The recent “improvements” with queued image syncing causes syncing to be significantly slower than it was previously due to inefficiencies in the algorithm.

  1. The algorithm does not recognize when several issues have the same cover image. Use “Duplicate” to make multiple copies of the same issue. (I do this as every comic/issue has a unique serial number that is the same as the index. We use a numerical filing system based on the index).
  2. The above mentioned algorithm causes cover images to be downloaded multiple times rather than just once. For me that is 12,000 images, mostly CORE images.
  3. A better system would be to hash unique images and resolve locally if a duplicate is requested. This would save much time/bandwidth and greatly reduce the time needed to sync a large database (feel free to use our database for testing).

The sync is in fact a lot faster for most of our users who use CLZ Comics for their personal collection.

Also, I’m sure you don’t have to download 12,000 images all the time? What are you doing? How come you have so many duplicates/why do you have to download them all, often?

Connecting images “that are the same” is not something we’re going to do for duplicated comics. It could cause a plethora of problems to be honest, (I’m afraid I’m not going to get into details though, as this is not a discussion forum on why we will or will not do things, but you’re free to suggest things).

Sorry it’s taking longer for your specific situation though.
