Remove __melange_queries logging
It causes the local instance to become very slow, as it has to pickle
all queries. A better solution would be to store them in the per
request value store and then add middleware to store that data at
end-of-request.
indexes:
# AUTOGENERATED
# This index.yaml is automatically updated whenever the dev_appserver
# detects that a new type of query is run. If you want to manage the
# index.yaml file manually, remove the above marker line (the line
# saying "# AUTOGENERATED"). If you want to manage some indexes
# manually, move them above the marker line. The index.yaml file is
# automatically uploaded to the admin console when you next deploy
# your application using appcfg.py.
