CQLC: Go Cassandra query returning page token for boundary limit?

[tanmay-saha]

In my Cassandra database for a particular query, I have 8 records, and I am using relops/cqlc library to query.

When I query with limit = 8, it returns 8 records with a PageState which is to be used as page token for the next set of results. First of all, I don't think it should have returned that PageState. And also as expected when I query again with that page_token and the same query parameters, it returns no data.

This is a representative of the way I am using to query

query, err := cx.Select().From(db.MY_TABLE).Where(db.MY_TABLE.NAME.Eq(name), db.MY_TABLE.EV_START.Ge(begin), db.MY_TABLE.EV_START.Lt(end)).Prepare(cass)
query.PageSize(8)
iter := query.Iter()
data, err = db.BindMyTable(iter)

err = iter.Close()
next_page_token = iter.PageState()

*cass is a gocql.Session

Why is it returning a value for the next_page_token?

The same thing does not happen if I increase the limit by one more, say 9.

Did someone else face a similar issue? Any hints as to what might be the issue?
