Thank you for the replies. I will try to answer all of your questions. @Kaan, yeah, wrong terms to use. But thats legacy SQL mindset in terminology :-)
I was doing the update via a remote shell. I used the following code to update: for ph in phs: ph.use_cc = True ph.save() The Phone kind has 12 properties. I looked into my index.yaml and there is no index with this kind mentioned in there. These are the stats on this particular Kind. So there were only 1616 entities I was trying to update. EntitesBuilt-in IndexesComposite IndexesTotal Size:697 KBytes5 MBytes0 BytesEntry count:1,61643,6420Average Size:441 Bytes127 Bytes Any pointers would be highly appreciated. If anyone can replicate this on their end, that would also be really helpful.
