Bulk allows a lot of record inserts to be done at once, good for initailly populating collections.

Populate MongoDB from another DataSource

dim cn as sql::Connection
cn.Open("::Name::AADemo-Northwind")

dim tables as c = cn.ListTables()
for each table in tables
	cn.PortableSQLEnabled = .t.	
	if cn.Execute("select * from "+table.value)	 then
		dim rs as sql::ResultSet
		rs = cn.ResultSet
		dim json as  c  = rs.ToJSON()
		dim mongo as extension::MongoDB = extension::MongoDB::Create("mongodb://localhost:27017","Northwinds",table.value)
		mongo.BulkOperation("{ \"insert\" : true , \"documents\" : "+json+" }")		
	end if
next

This example quickly populates mongo from the tables in Northwinds.
