Record 4.0

Special Record objects used in Zope.

Overview

Record provides special objects used in some Zope internals like ZRDB.

Records are used to provide compact storage for catalog query results.

They don’t use instance dictionaries. Rather, they store they data in a compact array internally. They use a record schema to map names to positions within the array.
