Todd Lipcon commented on KUDU-1872:
-----------------------------------
Directly exposing the existing PartitionSchema class as a public API doesn't
really work because it isn't designed to be ABI-stable. We'd need a PIMPLed
wrapper in the client namespace at least.
I think it's a mistake that KuduTable::partition_schema() exists as a public
method. It should probably be private since it returns a private type which
can't be used by client code anyway.
The work to provide a stable-ABI wrapper isn't too hard, just a matter of
getting it done :)

> The API allows to create and drop range partitions using:
> [AlterTableOptions#addRangePartition
> (Java)|https://kudu.apache.org/apidocs/org/apache/kudu/client/AlterTableOptions.html#addRangePartition-org.apache.kudu.client.PartialRow-org.apache.kudu.client.PartialRow-]
> or [KuduTableAlterer#AddRangePartition
> (C++)|http://kudu.apache.org/releases/1.2.0/cpp-client-api/classkudu_1_1client_1_1KuduTableAlterer.html#a521a968f4db133a10629f76c75dde793]
> - however it is currently not possible to retrieve information about the
> currently available partitions. In effect, when partitions are to be added
> dynamically by the client, they either must be optimistically added (i.e.
> ignoring AlreadyExists error) or tracked separately.
