This setting controls if the TRIMPush crawler will recursively collect the record numbers of the containers of each HP Records Manager/TRIM record.
When enabled a new metadata named
containers will be written to each extracted TRIM record with the
number of its parent records.
Collecting the all the parents of a record is usually an expensive operation, enabling it will significantly slow down the crawl. Unless you have a specific need for this metadata it’s recommended to disable this option.
