GAE Golang - queries not returning data right after it is saved

I am writing a Google App Engine Go application and I'm having problem in testing some functionality. Here is some sample code. The problem is as follows:

1. I create a new item and save it to datastore
2. I make a search query for that item immediately after (for example, getting all items in the namespace)
3. The item is not there

If I query for the item later (say, in subsequent pages), the item is found normally. I understand this behaviour might be intentional for apps deployed on GAE, but I would expect the local datastore to be instantly good for queries.

Is there any way I can force the datastore to consolidate and be good for such queries?

This is called eventual consistency, and it's a feature of App Engine's Datastore.

You can use a get method instead of a query to test if an entity has been saved.

In Java we can set the desired behavior of a local datastore by changing a run parameter:

> By default, the local datastore is configured to simulate the
> consistency model of the High Replication Datastore, with the
> percentage of datastore writes that are not immediately visible in
> global queries set to 10%.
>
> To adjust this level of consistency, set the
> datastore.default_high_rep_job_policy_unapplied_job_pct system
> property with a value corresponding to the amount of eventual
> consistency you want your application to see.

I could not find something similar for Go.
