POST /v1/rdir/meta2/fetch?vol=<volume ip>%3A<volume port>
Fetch specific meta2 records, or a range of records.
The record are ordered by container_url, so we can seek a specific prefix and start iterating from there.
For example, if we want to iterate through the containers that belong to account A, we’ll seek NS/A and start iterating.
If a prefix is provided, only records whose keys contain this prefix will be returned.
We can also seek a specific marker and start iterating from the record following the marker.
The marker is never included in the results.
A limit for the number of records to be returned can be specified.
If no limit is specified, the default limit be 4096.
The maximum allowed number of records to be returned is 4096.
If no more records are available for the requested subset, ‘truncated’ will be true, otherwise it will be false.
