A callback to determine whether relevant keys for this scan exist in a given table based on the table's properties. The callback is passed the properties of each table during iteration. If the callback returns false, the table will not be scanned. This option only affects Iterators and has no impact on point lookups.

参数:

tableProperties - the table properties.

返回:

true if the table should be scanned, false otherwise.
