Blobstore Google App Engine read consistency -



Blobstore Google App Engine read consistency -

does blobstore guarantee read consistency without write limit?

i know google cloud sql does

and datastore (but imposes 1 sec write limit)

however can't find info on blobstore

i've found blobstore perform fast , without consistency issues. if have process writes 1mb @ time perpetually, , starts few milliseconds later , starts reading blob, results in real-time long initial post didn't fail. in other words, can read blob parts (aka byte ranges) fast written.

not sure how useful real usage of blobstore, if need read parts create image or binary, it's illustrate reply bit. correct, there no clear throughput/consistency documentation because doesn't quite work ndb , google claims true limit http connection:

google app engine includes blobstore service, allows applications serve info objects limited amount of info can uploaded or downloaded on single http connection

(from https://cloud.google.com/appengine/docs/python/blobstore)

not sure if useful, wanted share twitter's version of blobstore: https://blog.twitter.com/2012/blobstore-twitter’s-house-photo-storage-system. i'm sure have made improvements, core philosophy shared google's blobstore implementation.
