I've been having problems with two descending __key__ indexes on my
app. Today I deleted and rebuilt one of the indexes, but the new index
is still missing up to 56% of items compared to the normal ascending
__key__ index. Here's my index definition from index.yaml:
- kind: domains_domain
properties:
- name: __key__
direction: desc
Here's a simple page that demonstrates the problem, showing the
missing items in red:
http://scoretool.appspot.com/domains/descending/
Additional info about my app: I have a large dataset (2 million items
using 15.7 GB including metadata). The key names are short ASCII
strings. Index building or deleting takes several hours, but it seems
faster today than before SDK 1.2.8 came out.
Corrupt indexes are a significant problem for my app because it
compares ranges of key names on different models to update or delete
objects. Please let me know if I can do something else to help
diagnose this issue.
