If the specified zone does not exist in the specified data
source, <command>b10-loadzone</command> will first create a
new empty zone in the data source, then fill it with the RRs
given in the specified master zone file. In this case, if
loading fails for some reason, the creation of the new zone
is also canceled.
Due to an implementation limitation, the current version
does not make the zone creation and subsequent loading an
atomic operation; an empty zone will be visible and used by
other application (e.g., the <command>b10-auth</command>
authoritative server) while loading. If this is an issue,
make sure the initial loading of a new zone is done before
starting other BIND 10 applications.
When re-loading an existing zone, the prior version is completely
removed. While the new version of the zone is being loaded, the old
version remains accessible to queries. After the new version is
completely loaded, the old version is swapped out and replaced
with the new one in a single operation.
with the new one in a single operation. If loading fails for
some reason, the loaded RRs will be effectively deleted, and the
old version will still remain accessible for other applications.

The <command>b10-loadzone</command> tool periodically
reports the progress of loading with the total number of
loaded RRs and elapsed time. This option specifies the
interval of the reports. If set to 0, status reports will
be suppressed. The default is 10,000.

Specifies the RR class of the zone.
Currently, only class IN is supported (which is the default

Specifies configuration of the data source in the JSON
format. The configuration contents depend on the type of
the data source, and that's the same as what would be
specified for the BIND 10 servers (see the data source
configuration section of the BIND 10 guide). For example,
for an SQLite3 data source, it would look like
'{"database_file": "path-to-sqlite3-db-file"}'.
<simpara>This option currently cannot be omitted. In a future
version it will be possible to retrieve the configuration from
the BIND 10 server configuration (if it exists).

The name of the zone to create or update. This must be a valid DNS
domain name.

A path to the master zone file to be loaded.

The <command>b10-loadzone</command> tool was initial written
by Evan Hunt of ISC.
A prior version of the <command>b10-loadzone</command> tool was
written by Evan Hunt of ISC.
The new version that this manual refers to was rewritten from
the scratch by the BIND 10 development team in around December 2012.
As of the initial implementation, the underlying library that
this tool uses does not fully validate the loaded zone; for
example, loading will succeed even if it doesn't have the SOA or
NS record at its origin name. Such checks will be implemented
in a near future version, but until then, the
<command>b10-loadzone</command> performs the existence of the
SOA and NS records by itself. However, <command>b10-loadzone</command>
only warns about it, and does not cancel the load itself.
If this warning message is produced, it's the user's
responsibility to fix the errors and reload it. When the
library is updated with the post load checks, it will be more
sophisticated and the such zone won't be successfully loaded.
There are some other issues noted in the DESCRIPTION section.
