Cloud Datastore - Entity Count Query - StructuredQuery.Builder - Allow limit of 0

[codeconsole]

This API should be feature comparable to the standard API. 1 such feature that is missing is a count query which can very easily be implemented according to this ticket that was just closed:

#5061

All that is necessary is 1 of 3 things.

1. Don't implement it, but allow a user workaround by allowing setting a limit of 0. Why not? You can do it with other APIs.

2. Implement it as described in the above ticket (which works), add a count method, and maintain the exception of no allowing limits of 0.

3. Do both.

Either way, I don't quite understand the special java implementation that throws and exception with a limit of 0 is set considering this serves a purpose and is allowed by other APIs.

@codeconsole thanks, I checked the document again and it says limit >=0

[codeconsole]

@ajaaym That's an even better reference ;)
So is it possible that we can get the Java API to reflect this?

[ajaaym]

@codeconsole yeah we will have PR soon.

Thanks guys,

Any chance on adding null value binding support to Gql query?
