Question

My GAE app has no indexes in the Datastore Indexes tab, it stores only temporary data in the Blob format (never more than 1 meg, that is, only 1 blob entity), but still, it makes about a thousand Index Writing Ops, and the “used” proportion of the datastore keeps growing.

I know there is a possibilty to purge the indexes by using a command line utility Google provides with the SDK, but is there a way to completely avoid indexing the data that should not be indexed at all? Or at least purge them from the app itself?

UPD: I use Java.

Answer 1

I found a very simple solution to this thing: you can tell GAE that a certain property should not be indexed by using JDO annotations:

    @Persistent
    @Extension(vendorName = "datanucleus", key = "gae.unindexed", value = "true")
    private Blob b;
