Bug report

Windows 10 20H2 and 21H1

What version of osquery are you using?

OSQuery 4.9

What steps did you take to reproduce the issue?

Create a extended plugin with virtual table defined. Create a virtual table with primary key defined. Schedule a 5 minutes query for this table (Contains Union and not exists). See lots of callbacks (ExtensionImpl::call) with the registry as "table" and "action" as "generate". Looks these callbacks increase with the table record sizes increase. With the table records size as ~2000, see 11000+ callback in 45 minutes.

What did you expect to see?

As the query is executed every 5 minutes, see only 1 query in 5 minutes.

What did you see instead?

The queries are based on the table records size instead of the query interval.
