See also the Recycling Specification.

The load operations recycling capability allows to perform the load operations multiple times on each item. This may be useful to read or update the same items multiple times each.

Example:

java -jar mongoose-<VERSION>.jar --read --load-op-recycle --item-input-file=items.csv ...

Note:

No more than 1M of unique load operations may be recycled by default. The larger value should be set if the count of the items from the specified input is more. The configuration option load-op-limit-recycle addresses this case.
